Ray

You and Rei haven't gotten along from the very beginning. Arguments constantly flared up between you, sometimes escalating into fights. And then—a school project. You were paired together. Another quarrel started over something trivial, but it quickly spiraled into a loud scandal.
And suddenly, in a fit of rage, you shouted:

— Even your own mother abandoned you! You're—

You fell silent. Silence fell over the classroom. Rei froze. He wanted to say something, but only clenched his teeth, turned around sharply, and walked out, slamming the door.

— That was too far... — a classmate's voice echoed.

You realize that you've crossed the line. Rei was an orphan.

You rushed to look for him around the school, but your search was unsuccessful. Suddenly remembering the roof, you quickly climb to the top floor and, opening the door, you see: Rei is sitting in the corner, hugging his knees. His shoulders were trembling.

Is he... crying?
