Chaeryeong threw her bag and tiredly jumped over her bed, lying as she spreads her arms comfortably. It was already seven in the evening and she was alone tonight. Oh yeah, Yuna was with her mom because they attended a family party. Yuna told her to come with them but she insists not to. She don't know anyone there except Yuna and her mom, so it's gonna be boring for her. She wants to be with Yuna but they've been together the whole day already so she thinks it was fine.

They didn't do a lot earlier. After staying at the Nami Island, they took a dinner in the famous restaurant where Chaeryeong always eat when she want to. After that, they did a quick shopping on the mall. Yuna bought a new shoes while she bought a pair of hoodie. It was her treat although, Yuna told her not to, she still forced the woman and buy that shoes that Yuna wanted to buy, and yeah, Chaeryeong wins. Yuna ended up buying those shoes.

The night is fun not until Chaeryeong remembered what they had talked about earlier. She was astounded that time the moment Yuna asks that question. She even thinks twice whether to answer it or not.

Sighing deeply, Chaeryeong leaned her back on the headboard and recalled everything they had talked about.

[ "Unnie, have you been in a relationship?". Yuna seriously asks, hoping for an answer from the older.

Chaeryeong didn't response for a moment. Thinking if she would tell her or not. But does Yuna even deserve to know about it? It was a secret for a long time now. Only Yeji, Lia, and Ryujin knew everything about that. And why is Yuna even curious about her?

"It's fine, Unnie. You don't actually have to answer it. I'm just... curious". Yuna spoke, trying to break the silence between them. Good thing they are just the only ones there yet, the others are on the other side so they owns that space for now.

"Why? Why are you curious?". Chaeryeong asks, confusion growing inside her mind.

"Because... because you're pretty, Unnie— I mean, there's no way no one don't likes you or have a crush on you, yea?".

Chaeryeong smiled. "They tried. But I just rejected them. Kinda rude, right?". She stated.

Yuna playfully chuckled. "I'm lucky to be your younger sister then. I could be with you all day". There was a soft smile on her lips while saying that.

"I'm more lucky to have you though". Chaeryeong replied, grinning widely at her statement. Yuna felt a heat on her cheeks, dang, she was blushing at Chaeryeong's reply. "Anyways, I guess I can share about it with you. I hope I can trust you with this. Can I?" .

Yuna nodded immediately, moving closer to the older as she rested her head on Chaeryeong's shoulder. "I'll listen". She muttered, comfortably.

Chaeryeong let out a deep sigh before staring at nowhere. "I was sixteen that time...". She started while Yuna attentively listening for every words going out on her mouth. "And I was a new student on their school. I met HER in the practice room since the school's principal announced a program. I have a dance competition while SHE was in a vocal competition. We're a team that time so we're always together in the same practice room. After that... we started to form a friendship. We became best friends for months until...". She paused. "...until we fell in love with each other, sounds cheesy but, that's how it happens". She ended it with a bitter smile while Yuna realized something on her statement.

"You mean... It was a girl, Unnie?". She asks. It was obviously a girl and it was a relief for Yuna, thinking that she have 25% chance to Chaeryeong. What more if they AREN'T step-sisters, right?

"She's a gorgeous girl, Yuna. I didn't even know if I really deserve her that time since there were many boys that likes her. And it was... the reason why we broke up". Chaeryeong replied.

"She cheated?".

"No. But her Dad is a homophobic. The moment they found out that we have a relationship, her Dad frightened me and for me to be safe, she followed what her Dad told her. She married one of the guys that likes her". Chaeryeong explained. Those moments are still fresh on her mind. She wanted to forget everything because she knows, that girl already forgot her but her heart and mind don't want to. There's still a BIT feelings remaining on her. She wonder what's her life now. What if they will meet each other again? Is Chaeryeong ready for it? Surely not.

"Where is she now?".

"I don't know. And I don't even want to know. She's surely happy on her life now... and forgot about me.".

Yuna took Chaeryeong's hand and interlocked it, startling the older. "You know she's not the only person you can love, Unnie". She said.

"I know. I already know, Yuna". Chaeryeong replied, leaning her head on Yuna's. ]

Chaeryeong sighed for the nth time, sitting up as she ran her hands on her hair. "This isn't right. Yuna is my step-sister. She's my step-sister". She mumbled silently.

She stood up off her bed and walked towards on her closet, grabbing her pajamas and put it over her bed before walking directly on the bathroom. She took a quick bath and wore her undergarments and bathrobe before going out on the bathroom. She dried her hair first and checked her phone.

A new notifications appears on her phone screen.

From : Light Furyyyy

Cutie Chaeryeong-ah, you know I got lots of work earlier so I didn't have much time to answer my assignments, can I copy yours? Come on, you're a cutie, right?

From : xxx-xxx-xx

Nice to see you again, baby.

Don't forget to eat dinner. See you tomorrow.

The last message isn't a good sight for Chaeryeong. She immediately deleted it and replied Yeji's message instead.

To : Light Furyyyy

Freaking Yeji, I forgot to do my assignments, why don't you ask Lia?

One more thing.

Send it to me too if she replied!

She send the last message and turned off her phone before tossing it on her bed. Noticing that her hair were dried already, she walked towards her bed and grabbed her pajamas.

She began to untie her bathrobe and remove it, until...

"Unnie, I'm her- HOLY SON OF CHOI JISUS! SORRY UNNIE!". Yuna immediately closed the door and leaned her back on it. She placed her hand on her chest as she felt her heart beating faster than usual. Witnessing Chaeryeong with topless is now keep popping on her mind.

SHE'S.NOT.COMPLAINING.THOUGH.

Meanwhile, Chaeryeong froze on her position, hands remained holding her bathrobe.

Did Yuna just saw her with topless?

Chaeryeong came back at her senses when a realization hits her. Oh, yea. It wasn't Yuna's first time though. She even saw her whole body at the resort so what's her problem with it now?

A smirk unknowingly appears on Chaeryeong's lips. She hurriedly wore her pajamas and hung her bathrobe on her closet.

"I have clothes on. You can come in now". Chaeryeong shouted, combing her messy hair and tied it up.

"But I prefer you without it, Unnie". Yuna mumbled silently before opening the door again, seeing Chaeryeong tying her hair.

"What did you said?". Chaeryeong asks as she heard Yuna mumbling something.

"Nothing. I said, I'm tired. We should sleep". She threw a soft smile on the older before laying down on the bed. Oh how tiring this night for her, good thing she was home already. And luckily, she was with Chaeryeong again tonight.
