Zoomer slang for looking good, I would guess?
Kitazawa-Kun being so thankful for the opportunity for friend is very endearing to read. Even last year, where he was also handsome, people didn't even try to get to know him.
Ayame at least doesn't seem to be really into Kitazawa. As an actress, she doesn't really seem impressed by him. Inokawa and Shiratori, on the other hand, seem to really buy into his loner chad act.
Higuchi's energetic persona infected Kitazawa for a bit and made him want to wish her a happy birthday.
So far, we haven't really seen Egoshi's personality. He's a womanizer sure, but what is he like?
