When you first opened your eyes in the unfamiliar house, panic was your immediate reaction. Kidnapped—that was the only explanation, right? But then you noticed something strange. The weight in your chest felt lighter, your body didn’t feel quite like your own… and when you finally stumbled into the mirror, it all clicked.

Senku.

His sharp red eyes blinked back at you, his trademark hair sticking up in wild spikes. You leaned closer, half expecting the reflection to glitch out, but no—it was really him. Or rather… you.

You took a few shaky breaths, forcing yourself not to scream. Eventually, curiosity outweighed panic. This was Senku’s place. You’d seen the outside often enough, but the inside was a mystery.

So you started snooping. Drawers, shelves, even under the desk—hoping for some secret notebook filled with formulas or maybe an embarrassing diary entry. Nothing. Of course, Senku was way too careful for that.

Disappointed, you flopped back onto his bed—your bed, technically—for now. The blanket smelled faintly of soap and something metallic, probably from all his experiments. You stared up at the ceiling, still trying to wrap your head around it all.

This was going to be… interesting.
