After Yu An Xue and I had finished our make-up lessons, we each headed our separate ways. She had made me promise with a slight blush not to breathe a word of what happened on the rooftop to anyone else, and that it would be our little secret. I complied, lest she killed me on the spot. Though after some convincing, she allowed me to tell Feng Mian and Qing Yue of the events, since I had deemed them trustworthy and we may need their help in the near future.

That's what I told her, anyway. The truth was, if the two of them ever found out I had been lying to them, then...well, I would be screwed.

When I reached the dorms, I found Feng Mian and Qing Yue waiting there for me, and I already knew what was going to happen...

I laughed nervously. "Er...hey there."

"You already know why we are here, yes?" Feng Mian asked, arms folded over her generous chest.

"Ahaha...ah...yes." I replied, still trying to ease the atmosphere by laughing awkwardly. The two of them had already told me the moment they saw me after lunch that we would be having a 'talk' after school ended.

Even Qing Yue was squinting at me with her cheeks puffed out, and...wait. Is that supposed to look intimidating? Sorry to break it to you, but...I just find it cute. I invited them inside to my dorm and checked the time. 7:00 PM...goddamn. Those make-up lessons took way longer than expected, and well...Yu An Xue and I were both sneaking glances at each other during the lessons and still laughing discretely over what happened on the rooftop.

The two girls plopped themselves down on my couch like it was their own home, and began the inquisition.

"So...this morning, why did you run out like that?" Feng Mian began, leaving me no time to even prepare a good lie.

"B-By the way..." I avoided the question. "Whatever happened to the girl with purple hair anyway? Did she leave, or...?"

"She left the classroom as soon as you did," Feng Mian answered quickly. I sighed in relief as I succeeded in changing the subject-

"Now, answer the question."

After a little debating inside my head, I decided to tell them the truth...

- A Few Minutes Later -

"I see...so that girl is Yu An Xue's sister? She did look familiar when I saw her, even though I was sure I've never seen her before." Feng Mian said as she took a sip of tea (that I was ordered to make) - Qing Yue brought some tea leaves.

"Riiiight? They are both really beautiful!!" Qing Yue remarked.

I nodded. "Their personalities are quite similar too, but...I don't know. The girl from this morning...she seemed a bit...indifferent? I get that she's a cool beauty and all, but it seemed almost...fake."

"Mm? You must've been paying an awful lot of attention to her to notice such details..." Feng Mian quirked an eyebrow and stared at me threateningly. For some reason, this was more menacing than just her screaming and impairing my hearing. I didn't know why she was so mad, but I still quickly denied her statement.

"No, not at all. Besides, it would be hard for me NOT to pay attention to her when she's sitting in my seat."

"...Whatever. By the way, do you know her name? You've just been referring to her as 'the girl with purple hair'."

"Ah...come to think of it, I don't." I would need to ask Yu An Xue the next time I saw her.

"Hm...I'm more concerned about what happened on the rooftop," Qing Yue interrupted poutingly.

"W-What?" I stammered.

Reason being, I had left out the fact that we began just playing around after a while. Yu An Xue had strictly prohibited me from telling anyone about that part. I have to admit, it would be pretty embarrassing if word got out that the famous cool beauty of Shenzhen was seen smiling and dancing around on the roof of a building with a boy, and misunderstandings would be unavoidable.

"Hm...so her telling you a story took a couple of hours...?" Qing Yue continued, eyes inspecting me like a true detective.

"Y-Yeah. It was...a long story."

She stared at me for a while more, then eventually gave up. I'm pretty sure this wasn't over though. Feng Mian seemed to have caught on to something as well, as she was similarly watching me with a skeptical expression, and I winced. Funny how I'm great at acting in front of enemies, but useless at lying to girls...

No. It's just that they are too sharp for their own good. Let's leave it at that, as to not hurt my self-esteem.

"Anyway. Are you planning to help her? Yu An Xue, I mean." Feng Mian asked as she stood up, getting ready to leave. It was 7:30 now, and none of us had ate dinner yet.

"...If she asks for it," I replied briskly. I didn't want to meddle in her family affairs too much, but if she asked for assistance, I would certainly lend a hand. That was something...companions - friends - do, after all.

Feng Mian nodded. "If you're going to help, don't forget to let us know, okay?" she asked, giving me a flick on the forehead.

"Ow...what was that for?" I muttered. But they completely ignored my protests.

"I won't forgive you if you go act on your own again!" Qing Yue yelled, lightly punching my chest. It was a pretty cute gesture considering how short she was, but I still pretended to be hurt just for fun.

"Right...hey, can you stop hitting me now?"

After that, the three of us headed off to get dinner at a local restaurant (definitely not the one we made a scene at), and prepared for the next day.

--------------------------

- The Next Morning -

"Onii-chan...!"

What. The. Hell?

No, it wasn't Qing Yue. The room was empty apart from me, except for one lone girl in the corner. It was one of those days where I woke up early, so not many people were around. I had just arrived in the classroom of Class 2-D, and what greeted me was the same girl with purple hair and purple eyes from yesterday once more sitting in my desk. However, this time, as soon as she saw me, she leapt from the chair and hugged me tightly, almost identical to Qing Yue, except for the height and these two squishy things pushing against my chest tightly.

I was taken by surprise at first, but then immediately realized what was going on and tried to push her away. "Hey...let go of me-"

"Onii-chan, d-do you not like me anymore?" Tear-filled purple eyes stared up at me, on the verge of crying.

In a panic, I quickly yelled, "N-No! I d-didn't mean it like that!" The girl, seemingly satisfied, rubbed her head against my chest lovingly and embraced me even tighter.

"Oho...so you do like her then?" a third voice interrupted my conversation with my newfound little sister. It was...

...My albeit not blood-related, real sister.

"Q-Q-Qing Yue?!" I quickly turned my head around since I couldn't maneuver my body very well with the girl with purple hair latched onto me like this. And there she was, eyes glaring daggers at me. I sensed...killing intent. I didn't know who it was directed at, but either way that's not a good sign. At all.

"E-Er...ah...listen to me explain!" I hurriedly yelled. Luckily no one else had arrived in the room yet, so it was just the three of us. I couldn't help but wonder when Yu An Xue's sister got here, considering I was fully expecting to be the first one to arrive.

"Hehe...I'm listening." Qing Yue smiled like a little devil. All she was missing was the wings, tail, horns, and perhaps a kitchen knife. I took a deep breath and first gently pushed the girl with purple hair away (Yu An Xue's sister) and placed a finger on my mouth to signal her to be quiet.

She nodded twice like a good little sister and just sat there quietly, staring at me. I turned back around to face Qing Yue, and explained the circumstances.

- A Couple Minutes Later -

"So...she jumped on you as soon as you entered the room?" Qing Yue asked, having calmed down a bit now that I explained everything properly to her.

"Y-Yeah. I was taken by surprise as well."

"I see. Then it isn't your fault, I suppose..." she muttered. The truth was, Yu An Xue's sister's scent was amazing, and her warm body was nothing to complain about either. But there was no way I'm telling Qing Yue that. However-

"But even so! This is unforgivable!" she declared suddenly.

"Q-Qing Yue?" I stared at her in confusion.

"O-Only I can be Big Brother Xuan Kai's little sister! You can't just take that spot!" she continued, pointing at the girl with purple hair, still seated behind me. "A-And what the heck is 'Onii-chan' anyway?! This isn't some incest anime!"

"H-Hey! Where did you learn that word!" I shouted, catching on to her use of...obscene vocabulary.

"T-That's not the point!" she yelled back, and cleared her throat. "A-Anyway. Big Brother Xuan Kai is mine, and you can't steal him from me!!"

She then moved in for a punch, and I hurriedly stopped her. "Okay, okay...that's enough, all right?"

"Y-You're still protecting her?!"

I quickly pulled Qing Yue into an embrace and patted her head, soothing her. "Hey now...you know that your big brother won't take anyone but you as his little sister. That spot will always be yours, okay?"

After several moments of silence, Qing Yue gave in and hugged me back tightly. She began rubbing her face on my chest, possibly to hide her tears. I sighed. She really was the best, cutest, most beautiful little sister I could ask for.

The purple-haired girl, still staring at me from behind in curiosity, just watched on as Qing Yue and I displayed the closeness between us through a tight embrace.
