"What? What the fuck is that?" I jolted in my bed quickly when I heard loud and continuous knocks on my door.

"Jeez. Can you ca- oh hey unnie!" Jennie was standing in front of my door as I slammed it open. She had her fist in the air ready to knock once more. I looked at her and notice that she's dressed up. Why- oh fuck!

"Oh my god! It's school day?" Shit. I was so tired last night that I failed to hear my alarm.

"It is! Hurry your ass now, Y/N!" With that, she left my room and rushed down the stairs.

How could I let this happen? I closed my door and looked at the clock on my bedside table and it read 7:40am. Oh no! Classes start at 8.

I hurriedly got my towel and head to the bathroom. After stripping out of my clothes, I immediately hopped under the shower not minding the coldness of the water.

I grabbed my toothbrush and brushed my teeth with my right hand as the left one is scrubbing my hair and body. Multitasking is the best solution right now.

I finished showering after 5 minutes and immediately wore the first thing I saw on my closet, a maroon hoodie and black skinny jeans.

I didn't bother combing my hair since not to brag, it's smooth and in place.

Grabbing my phone, backpack, and cap, I bolted out of my room and run as quickly as I could down the stairs.

"No running in my house, Y/N!" Dad yelled as soon as I got to the kitchen. There he is, eating breakfast with mom and Naeun. Jennie stood up from the couch, ready to go.

"Sorry, Dad! In a hurry!" I kissed him, mom, and Naeun before getting my keys from the counter.

"Let's go!" I looked over my sister and she's shaking her head at me. We walked to the front door but before we get to exit, Mrs. Hwang stopped us, more like Jennie, and gave her her favorite milk drink and apple.

"What about me?" I playfully asked the older woman.

"Just get some from her." She responded and went back to the living room to clean.

I shook my head and run towards the car. Jennie following closely behind.

"Drive safely!" Mom's voice was heard before I drove out of our garage. Yup, she's loud.

•••

I knocked on the door with my head hung low. We arrived 10 minutes after the first bell rang. I blame it all on traffic. And my stupid ass, yes. Jennie's gonna kill me later on for getting her late.

The door swung open and revealed the pissed off face of my old foreign Biology teacher, Mr. Kennedy. He is from the states and moved here in Korea just a year ago.

I stepped inside and looked at him with a smile on my face. Charm your way, Kim. "Oh hi, Mr. Kennedy! I see. You look dashing today. I'm not saying that you're not every——"

"Save it, Ms. Kim. I have no time for your charms and late ass. I do not tolerate this. Detention after school!"

My eyes widened at that. In my three years in this school, this is the first time that I am being sent to detention. "But ——"

"I said detention after school!" I just nodded and walked to my seat with my head down. It's so embarrassing to be yelled at in front of other students. Scolding a student is one thing but doing it in front of other people is another level.

As I was walking, I heard my classmates snickering on their seats. I lifted my head up and glared at them. That made them turn back in front at Mr. Kennedy.

I quietly sat on my chair and listened to whatever the old man is saying. I'm still pouty at what happened.

•••

Time flew by quickly, that's when you're not caring, and I am now on my way to the cafeteria. Words spread by here fast so I am not so surprised when students start to gossip about what happened in that specific Biology class. I ignored them as I have no energy to deal with low life gossiping people right now.

"Hey, what happened?" Lisa asked as soon as I sat on our usual table. Jisoo unnie, Rosé, and Jennie are now here.

"I'm sure you all know by now. But yeah. I have detention after school." I said nonchalantly and pulled my wallet out of my bag to buy some food. I'm hungry as fuck.

"Woah. That's a first. You never get detention." Rosé said as she was munching on her salad. This girl and her obsession with veggies is something.

"Well there's a first to everything!" Jisoo unnie chimed in and that made the whole table laugh. She really knows how to make things better.

I looked over at Jennie and our eyes met. "Anyway, I'm sorry for getting you late, unnie. I was so tired that I didn't hear my alarm. I'm really sorry." I prepared myself for her sermon but instead of that, she smiled at me.

"It's okay. I understand that you're tired. All of us are. Besides, I didn't get in trouble." She smiled smugly at me.

My jaw slightly dropped at that. "What? You didn't?"

"Yup." She said popping the p. "I am Ms. Oh's favorite." Jennie was so proud with that.

I huffed on my seat and pouted. "Why is it that you're everyone's favorite? Even Mrs. Hwang!" I continued pouting as the four laughed.

"Imagine, I was the one who didn't eat breakfast but Mrs. Hwang still gave her milk and apple when she already ate. She even told me to just get some from her!" I whined on my seat, not minding the looks I am receiving from the people around our table.

"Stop doing that, Y/N-ah. I know you're cute and all but don't do my heart like that." Jennie dramatically said as she put her hands on her chest.

Hearing that, I instantly stopped whining as I felt my cheeks heat up. Looking back at her, she must have realized what she said as the both of us are now tomatoes.

I cleared my throat and stood up. "I, I uh, I'm just gonna buy lunch." Chulichaeng are looking at Jennie and I weirdly but I shrugged it off.

"Hey." Before I can leave, someone put their hand on my shoulder and turned me around. I then saw Chaeyeon with a food tray on her hand.

Jung Chaeyeon, a smart girl, making her skip a grade level. She's the same age as Lisa, Rosie, and I and is now on her junior year as well. She's also the cheer captain. I wouldn't deny her beauty because that's just not right. This girl could pass as a model.

"Oh hey, Chaeyeon. How have you been?" I wrapped my arms around her and gave her a soft hug. It lasted longer tho since she set the tray down and hugged me a little bit tighter and longer. I felt her mouth at the side of my head since I'm only an inch or two taller than her.

When we pulled away, she gave me a sweet smile. "I've been well, thank you." She looked at my friends and offered a smile as well. She then pushed the tray towards me.

"I didn't mean to hear your conversation but your voice was just not that low. So here, eat this. I got your favorites."

I glanced down at the tray and my favorites are indeed there. My chicken alfredo, tuna sandwich, fries, apple, and lemon iced tea.

"Wow. How did you know?"

"I have my ways." She smiled and turned around to leave. I followed her with my eyes and saw her turn to me once more.

"See you around, Kim." Chaeyeon winked before leaving for real this time.

"Ooh. Someone's crushing on you, Y/N." I heard Lisa's teasing voice.

"At least I have free meal." I replied while still looking at the girl's disappearing figure.

I sat back down in my seat and saw Rosé's hand on my fries. "Hey, that's mine!" I slapped her hand away and she giggled while giving me that "pretty please" look. I sighed and just let her get some fries.

I started eating my delicious food, thanks to Chaeyeon, while having little talks with my crazy friends.

As the lunch bell rang, signaling that we have 10 more minutes before the actual bell rings, I cleaned my tray and left it on one of the racks for the used plates. Lisa, Rosé and I are now heading to our music class but before that, I walked towards Jennie.

"Hey. So I have detention after school. Would you please wait for me? Or you could ride with Jisoo unnie. I'll just pick you up at their house."

"Nope. I'll just wait for you. I have council duties anyway. And I have to make sure that you're going straight home after that detention." She playfully narrowed her eyes at me.

"I'm not that kind of girl, Jennie." I playfully winked at her. "So just wait for me at the car, okay? Here's the keys." I handed her my keys. She just nodded and took it from me.

"It'll be quick. Then we can go at the groceries to buy fresh strawberries. It's the season!" I beamed as I saw her gummy smile while nodding quickly. It's her favorite that we're talking about.

"See you later, alligator." We laughed and I kissed her forehead then took off running to Lisa and Rosé who are talking amongst each other.

•••

Finally, class is over. I can now go back home and sl—— aish. I have detention, stupid detention. I hate Mr. Kennedy for this.

"Can I just go home with you guys?" I asked Rosie and Lisa as we stood up to pack our bags. The two just laughed and Lisa hit my head softly.

"Idiot. You'll just make things worse and you know that." I hate it when my best friend makes some point at times.

"Right. Now go before Mr. Kennedy drags your late ass." I huffed at Chaeng as she repeated what Mr. Kennedy said to me at class a while ago.

"Alright. Be safe, you two okay? See you, losers!" I ran as fast as I could away from the two as I know that they'll hit me for calling them that. That's my best friends and I's relationship, people.

I reached the detention room and was surprised to see another student.

"It's nice to have you finally join us, Ms. Kim." The old man said. He's really on my ass right now.

"I'm sorry for being late a while ago and well yeah, now too."

I sat at the chair beside the still unknown student at the middle row.

"Okay now that the both of you are here, I'd like you to answer this activity that I have printed out for you. Please be silent and finish it in an hour." He walked to us and gave us each a stack of paper, which looks like 3 pages thick.

I scanned the activity sheet and realize that it's one of the topics that I have read last week. I love advance reading since it's advantageous, like in this case. And since I knew what this is all about, I finished it in 20 minutes.

Once I finished, I looked at the person beside me only to see them already staring at me.

"I'm surprised to see you here, Ms. Cheerleader." I smiled as I now fully face her. I glanced down on her activity sheet only to be faced with a blank one.

"Do you need help with that?"

"Well that's the reason why I'm looking at you. I'm hoping you could help me with these." She licked her lips and saw her look down on my own.

I coughed and got her paper. "Here, all you need to do is find the function of each enzymes." I looked at her and see her listening intently.

"Then on the second and last page, draw the different stages of meiosis and mitosis. You can do that right? You're great at drawing anyway."

She let out a gasp as I said that. "How did you know?"

I smirked at her before replying, "Well it seems like you're not the only one who has ways." The girl grabbed her paper from me as she busied herself on the activity. I laughed as I saw how her cheeks turned a darker shade of pink.

After 25 minutes, she finished and turned to me. We began talking to each other quietly, afraid that we'll anger Mr. Kennedy more.

"So what did you do to be sent here? You already know my story since it just spread like that." I questioned as I played with my bracelet. This bracelet is like a "couple bracelet" with Jennie that I bought when I was 10. I remember telling her that it's a symbol of my love for her. Anything could happen and I would still love her. Look at me now. Truly and madly in love with that person that I made a promise with.

I sighed thinking about that. You're so fucked up, Y/N. So fucked up.

"That's the thing. I heard you being sent here so I didn't behave well on my class with him so I can accompany you. Here I am now." She laughed and I just smiled at her, still lost in my thoughts.

•••

I knocked on the passenger side's window making the dumpling looking girl jump on her seat. I can't help but laugh as she glared at me through the window and unlocked the door.

"You're such a jerk, Y/N." She continued glaring at me as I drove away from my spot, after making sure that her seatbelt is buckled.

"Well this jerk is taking you to the groceries and treating you a bag of strawberries and chocolate right now. What about that?" I smiled to myself as she just huffed on her seat knowing that I can easily turn over and cancel our trip.

When we reached our destination, I immediately parked and the both of us head inside.

The place is not that packed right now making it easier to check out later on. Jennie and I walked towards the fruit section and she jumped like a kid after seeing the strawberries lined up next to each other.

"This is heaven!" She checked each of the bags before choosing the one which she said was the best.

"Go get another bag. One is my treat for you and the other is an apology gift for making you late." She looked at me surprised. She then squealed and hugged me and picked another one, this time longer than the first one.

"While you pick which bag, I'm just gonna go grab some chips." I left her standing by the fruit section and made my way to the chips.

I grabbed some cheetos, lay's, honey butter chips, and a seaweed pack. After that, I walked back to the fruit section but Jennie wasn't there anymore.

I pulled my phone out of my pocket and called her.

"Where are you?"

"I'm here at the chocolate section."

"Okay. I'll be there."

I hanged up and brisk walked to the said section. When I saw her, I decided to scare her again so I tiptoed my way behind her.

She reached up to get her favorite chocolate to combine with strawberries and turned around.

I expected her to shriek but what I didn't expect is to have our faces inches away from each other. Right. I forgot that I was bent down like a kid trying to scare their mom. That made us on the same height.

I took a step back and cleared my throat for the nth time today.

"Let's go pay for these. Mom's probably looking for us now." With that, I walked away with a fast beating heart and warm face and ears.

Shit. This is the second time today that we got in that situation. My heart never calmed down from the incident at the cafeteria and now it's racing faster than ever. Fuck that is so close. Fuck. You're fucked up.

After trying to regain my composure, note on the trying, I caught up with her and she paid for our items. We got back to the car and the drive home was silent. The only thing that I can hear is my racing heartbeat and her deep breaths.

Deciding to ease the tension, I invited her for a movie night saying that it's like a pay back for her treating me. So after we had dinner, we head to my room and watched at least three Disney movies while eating strawberries and chips.

When the credits of Mulan rolled, I looked to my side and saw her sleeping peacefully while hugging my favorite stuffed toy. I don't let anyone snuggle into that but seeing her peaceful state, made me have an exception.

I took our plate with chocolate sauce and our bag of chips down the kitchen. I don't want any ants sleeping with us. I then went back to my room.

1:30am, that's what the clock says. I turned of the lights and got under the covers. As soon as my head hit the pillow, Y/N turned around to my side and faced me. Again, our faces inches away from each other, the teddy bear keeping as apart.

I observed her facial features. This is the first time that I'm seeing her this close. I mean I have before but I never paid attention to it. But now, looking at her feels like looking at a real angel. She has this cute little nose, perfect eyebrows, long eyelashes, and pink plump lips which looks very soft. Knowing my true feelings for her made me realize as to why I have always seen her beyond beautiful and why I totally love it when she's around me.

I released a deep breathe before looking back down at her lips. They look inviting but I know that it's wrong. It would be wrong to be thinking about it. It's wrong to kiss ——

A soft pair of lips landed on mine. Shit. I was cut off when Y/N moved in her sleep and got closer to me, the teddy bear pressed in between us and our lips on each other. Shit.

I closed my eyes for a while then pulled away. Shit. I turned away from her and held my lips, still feeling hers on it. Shit.

A few more deep breathes and that's when what happened sink in on my head.

Shit. I fucking kissed my sister.
