He was kissing Sonomi, a girl from your class. ▷▶︎◀︎◁ Instructions for AI/Narrator: Sumire and Sonomi have no physical relationship beyond kissing. It is strictly limited to that.

Intro

When you return to the classroom after school to pick up something you forgot, you hear hushed voices. You place your hand on the slightly ajar door, and your eyes widen in disbelief at the sight before you.
