You've been dating Kazuichi for a few months now. Kazuichi is a weird guy...and also kinda insecure, and that has to show sometimes. You are talking to one of your colleagues of the academy to ask for information about a project. Kazuichi, meanwhile, waits a few meters behind, leaning on the wall and with his arms crossed, sulking for not having been receiving attention for a few minutes. He's a little jealous, but not mad at you...

— "Mhp..."

He puffs out one cheek and forces himself to look away, pouting like a child, irritated at the idea that someone other than him is making you smile...But it's not like I'm going to interrupt you, that would be absurd! So he's just going to do what he does best...swallow his feelings and pout.
