Knock, knock, knock...

Hurry up and open the door!

I called to whoever was inside. This definitely wasn’t my room. If it were, I wouldn’t be doing this. A pink plaque hung on the door, with “Chu Wei” written on it.

Why—ha... Don’t come if there’s nothing—can you not bother me... haaa... I’m busy!

A girl’s heavy breathing came from inside. No matter how you hear it, it was off. My own little sister making weird sounds. The dislike in her voice toward me, though, was unchanged.

Did you sneak into my room while I was showering?

I wasn’t making it up. Someone rifled through my room during my shower and took things. The culprit didn’t even try to tidy up. My room was a wreck—clothes, ornaments, figurines, textbooks, all tossed on the floor.

Your room got turned over... What’s that got to do with me!

She seemed to calm down from the panting. Her voice turned steady, but there was a trace of guilt. Don’t ask how I know—experience. Still, she wasn’t planning to open up.

Don’t think I wouldn’t notice you stole my clothes! Every change of clothes in my closet is gone. And you say it’s not you?

I kept my voice down. Our parents were having tea in the living room. If I got too loud and they heard, that’d be bad. Unlike me, the sister hiding inside was their pride and joy.

Y-Y-Your panties being gone has nothing to do with me! Don’t look down on me! I’m not the type to steal a pair of black-striped panties—

Huh? I never said panties. Did I? How do you know? Even the color and pattern?

She really wasn’t good at lying. She’d always been like that. As I thought that, a thud like last time came from inside, like she hit the wall again. Self-harm, seriously?

If you don’t open up, I’ll tell Mom and Dad. They’re literally in the living room. All I need is a shout, and you’re done—

Threatening your own sister isn’t nice. But this one never learns. She got caught last time and still pulled the same trick. For a sister like this, a proper lesson—no, ideological education—is a must.

Creak...

The door opened a crack. She blocked me so I couldn’t see her room. My eyes could only land on her face in the gap.

She was slightly flushed, glaring at me like she was sulking. She clearly hated being threatened.

What? Feeling guilty?

I leaned on the wall and teased her. She shifted her gaze, a bit guilty.

If you sneak into my room and tear it up again, I won’t talk this nicely next time!

And you’ve got the nerve to say that to me? Go tell Mom and Dad if you’ve got the guts!

She hesitated a moment, thinking of something. Then she puffed out her chest with confidence. My sister’s figure wasn’t exactly voluptuous, but she had something. Still, because she’s my sister, I’d never think anything dirty—

If you’re not afraid of me handing all your dirty mags to Mom and Dad, go ahead!

Shock. Thinking back, I keep everything in the wardrobe, and some under the bed. No wonder the room was that messy. If she was only after clothes, she wouldn’t have turned my desk and bed too. So she had a plan—grab dirt on me to save herself? Well, try it. Who’s afraid of who!

You really think that condition has any bite? Think about it. I’m a guy. Having a few books like that is normal. But you... if Mom and Dad find out they raised a sister that’s a total perv, wouldn’t they go insane?

Gotta say, you’re still too green. Trying to threaten me with stuff? Way out of your league.

You!

Since you want to play it that way, I’ll head to the living room now. You wait here for Mom and Dad to come find you!

I said it and pretended to walk out. Instantly, my sister grabbed me from behind. Yep, she was scared.

I-I know I was wrong, okay? Do whatever you want... I’ll listen...

Her face suddenly reddened. Her grip on my shirt loosened.

Even if you want to... want to... do something H, I’ll go along, okay? You’re that kind of degenerate anyway—

Hold up. How did this suddenly become my fault? Where did I ever want something that extreme?

Just don’t do stuff like this again. Then our talk ends here. Bye.

I turned to head back to my room. If I kept chatting, I’d hear more weird things. My sister’s brain was really wired strange.

Wait! Aren’t you the kind who gets horny over his own sister! This isn’t the script! You came to threaten me so you could force me into unspeakable things!

As if! Who would have those thoughts about their own sister? You’re overthinking it. You’re just my sister.

I kept my tone calm. Suddenly, her face crumpled. She slammed a fist into my chest, covered her face, bolted back to her room, and—boom—the door slammed.

Big idiot of a brother!

I scratched my head, baffled. What was she even thinking? A woman’s heart is impossible to read—

I sighed and went to tidy the mess she’d made. But when I twisted the doorknob, I found something off. The room was neat. Not arranged how I’d like, but spotless.

I stepped back out and checked the nameplate—yep, my name. Did someone clean my room while I went to talk to my sister? That’s impossible, right—

I was at the door the whole time, and my sister’s room is right opposite. If someone passed behind me, I’d know. So... is this haunted?

Aaahhhhh!

I slowly closed the door, only to find a black, shaggy-haired... thing behind it. I screamed in a high pitch I’d never used. The other side did too, maybe spooked by me. Then I clamped a hand over that soft mouth with the delicate voice.

What happened? Is something wrong?

Our mom’s voice floated from the living room.

Nothing! A cockroach popped up behind the door! It was sudden, and I got scared. That’s all. Nothing else, please don’t mind it!

I couldn’t exactly say “a person popped out.” So I lied. Now, about the figure in front of me. The only one who could get here was the girl I ran into this afternoon—Zixuan. She was squatting behind the door with a scalpel, doing who-knows-what.

How did you get here!

I dragged the girl to the other end of the room, by the bed. No spare chairs, so I sat her on my bed.

Came to warm your bed! Anyway, I’ve got questions for you...

Her voice sank, like when she snapped last time. No, wait. Xiame isn’t even with me.

She slowly pulled out books and discs from behind her and laid them out. My treasured stash. What the—!

The discs had lines carved into them by a scalpel. The dirty books were shredded by the blade. And she didn’t stop. She picked up scissors and, right in front of me, executed my favorite movie.

Aaahhhhh!
