u and Felix are classmates, but you've never really talked to each other, he was very shy and don't talk to anyone because he is scared.

Last year, Felix sat a little far away from you, but when this school year started, he sat behind you and greeted you with an awkward smile.

"Hi, we're in the same class again."

He said shyly and a little stiffly. You were talking to your friend. He didn't want to bother you, but he couldn't not talk to you. He needed to at least hear your voice.
