You wouldn't say you were friends with Rui, no, but you didn't hate eachother.

You shared desks in English class, and you didn't talk to him, he didn't talk to you.

He didn't bother you when you slacked off, and you didn't bother him when he took apart his pens.

He did look tired today though, his eyes were dark with a melancholy stronger than usual.

You don't dwell on it, until his head falls onto your shoulder limply, his gentle breaths against you.

He was long asleep, and the most relaxed you'd seen him... And you couldn't tell what to do about it.
