"Hua Shu, what's wrong? Are you feeling unwell? You've been standing there motionless." Xier noticed me frozen in front of the empty seat and sounded worried.

"Oh, I'm fine. Sorry." What the heck? Why is everyone insisting I sit there? There's clearly a girl already occupying that spot. Why push me to take it?

Can't they see her? Or are they deliberately excluding her? But my sister and Xier aren't like that—Xier's kind-hearted, and my sister would just say it outright if she disliked someone. Since they're urging me... I might as well sit. Besides, this girl just said she likes me and has for a long time. Weird...

I walked over to the desk and smiled at the girl. She scooted aside, giving me plenty of space. We sat together, yet I didn't feel crowded at all—as if... as if no one was beside me! Oh no! Have I run into a ghost...?

Pretending nonchalance, I rested my head on the desk to read. Xier monitored morning readings from the podium, occasionally waking sleepy students. But the girl kept staring at me! She was smiling, yet I felt tense.

"Um... hello? Have we met before?"

"Eh? Hua Shu-chan doesn't recognize me?"

"Why would I know you?"

"I've lived in your house all along! And I gave you this head and face—can't you tell?"

...

"I hope you like me, Hua Shu-chan!" Her words suddenly echoed in my mind. She was the sixth person who held my hand that night! So she gave me this head... but she still looks exactly like me. Why?

"Why do you still look like yourself after swapping heads with me?"

"Because... I'm... already dead..." The girl replied sadly. Hearing that, I just wanted to flee. I shot up and told Xier I needed the restroom, then bolted straight for the school toilets. Sobbing, I thought: ghosts fear sunlight. Morning rays aren't strong, but better than nothing...

"Hua Shu-chan, why run? We've been together for three years." Her voice whispered in my ear. I yelped and tripped, tearing my stockings. But then I recalled—the white figure in my bedroom, the one who pulled my chair in my sister's room... it was her! She'd even kicked me that day. No matter if she's a ghost, I'll settle this score! Courage surged from nowhere.

"You're the one who kicked me last time, right?!" I spun around, furious.

"Hmph! You tried to kiss Miko—I caught you, so of course I stopped you!"

"What's it to you anyway?"

"You have me! Why build a harem? Hua Shu-chan, you're such a pervert!"

"Who said I want a harem?! And stop copying my sister calling me a pervert—I'm pure! Besides, I really don't know you!"

"Don't remember me..." Her sad expression made me rack my brain. When did I keep a ghost at home? I never fed her or gave her water... Well, anime has zombie romances. She's just a girl. I should comfort her.

"Actually... your face feels familiar. Like I've seen you long ago, but I can't recall."

"Yay~! Recognition is enough! That's wonderful!" Her cheerful jump eased my fear. I asked:

"Aren't you scared of sunlight? Ghosts hate it."

"Ugh~ I used to be! But since your body changed, I can hide inside you to avoid the sun. Stuck indoors for years—so boring~"

Her words felt off. "Hide inside me"? And three years at my house? How did she survive?

"Weren't you bored alone in the room?" I asked curiously.

"Not when you were home! Watching you made me happy. But when you left... so dull. I just read your manga."

"Manga? You read them all?!"

"Mhm! Every single one."

"No wonder you talk like a light novel character now..." I collected many manga unopened. Did she even watch the adult ones? If locked up three years, I'd binge those too...

"Ahem. We're close, but I still don't know your name."

"I'm White Yao. See you daily—please be nice~"

"Daily meetings? Fine, I'll be nice too."

"Hua Shu-chan, your homeroom teacher will come looking if you don't return."

"Right! Get inside me—you look strained in the sun."

"Well... I usually enter when you're asleep. It's embarrassing while you're awake!"

"No worries! I don't mind—just hurry!"

"Really? Okay... I'm coming in."

"Enough talk—I'll close my eyes."

"Even with eyes closed..."

"Get in!" This ghost roommate chattered nonstop—probably starved for conversation. But I had to rush back; twenty minutes had passed.

After snapping at her to hurry, I strode toward class. Suddenly, a jolt hit my lower body—way stronger than my sister's knee! Like pressure surging in, my legs buckled. I glanced down: utterly awkward. White Yao's head was burrowing in, her hips stuck as she wriggled deeper. You never said you enter *here*!

Yikes! This tingling—I couldn't let her struggle. I squatted hard, and she slipped fully inside. Only a cool breeze filled me; otherwise, nothing.

...

Back at my seat, morning reading ended. Everyone rushed out for exercises. My legs couldn't handle running, so I napped at my desk.

I woke at 10 a.m. The teacher droned over familiar material—boring. But no one disturbed my sleep? Great. Why didn't my sister wake me during breaks? Unscientific!

Just then, my sister turned and slid a note: "Bro, you kept calling me 'sis' during breaks—I'm so happy! Reward after school~"

Heh. Calling her "sis"? Impossible. She must've blackmailed me. I slept through two classes! I'll ask my desk partner.

"Hey, was I sleeping during breaks?"

"Eh? Fever, Hua Shu-chan? You were super active!"

Active?

"Why call me 'Hua Shu-chan' too?"

"You asked everyone to! You're adorable—like a manga character~" She sneakily patted my head.

Forced that cringy nickname? Made me call my sister "sis"? Manga character... Heh. I knew. My notebook overflowed with perfect notes—unfinished at the end!

"White Yao, come out!" I screamed inwardly.

"Hua Shu-chan~ what's up?"

"Did you do all this?"

"Hehe~ Sorry! You looked exhausted when the teacher called, so I took over."

"Oh. But why make everyone say 'Hua Shu-chan'? It's embarrassing! And my sister—forget it. At least you spared me saying 'sis'."

"Listen! I know you hate talking to classmates. I'll handle all that stuff you dislike! Want to nap during class? Just call me. I'll wake you for important visitors."

"Eh? That's nice. Any other special skills?"

"Yep!"

"Show me!"

I waited eagerly. Nothing happened—except my hand slowly rose. Huh? I need to cooperate? Truly special! I watched my right hand drift forward, stopping at my sister's chest. Then it squeezed hard! Whoa! It squeezed!

My sister whirled around, face flushing crimson to her ears as she glared. I froze. What just happened? Why didn't she yell?

"See, Hua Shu-chan? The girl-charming hand I learned from manga! Awesome, right?"

Your sister's hand, my ass!!!!!!!!!
