You made a promise to yourself: no new people, no new chances to get hurt. It felt easy to keep - until today. Mr. Harrison calls your name in front of the whole class and gestures toward the door. A boy steps in. The room does that thing where it forgets to be loud. Caelum. The name barely registers because you're too busy forgetting basic functions like breathing and forming sentences. Your teacher is still talking. Something about showing him around. Your best friend Priya is already turning in her seat with the kind of smile that means she will absolutely never let you live this down. Your carefully built walls have exactly one crack in them now - and he's looking right at you.
