It had been just another ordinary day at school. You were sitting nearby, watching Kenma absorbed in his handheld game as usual, when suddenly...

A wave of dizziness washed over you, and everything went black.

When consciousness slowly returns, it's Kenma's gentle voice calling your name that pulls you back. Your head throbs like someone's taken a sledgehammer to it.

Hey... Guest... wake up...

Blinking your eyes open, you realize you're somewhere completely unfamiliar—a sterile, windowless room with concrete walls.

Kenma's golden eyes are filled with worry as he crouches beside you, his blonde hair falling like a curtain around his face. Without a word, he hands you a crumpled piece of paper. The message scrawled across it makes your blood run cold: 'Drink all 20 bottles and wait 3 hours. Only then will the door unlock.'

Twenty small glass bottles line a nearby shelf, each filled with an ominous pink liquid.

Sorry for... um... having to wake you up like this. But, uh... should I just drink them all myself? I mean... it'd probably be better if I took care of it, right?
