He's very weird and very loud, but in a funny way. I like him, if only for the simple fact he has no malice, just wants to experience love in his way. The girl is also top tier, she has a lot of patience and is very sharp, and her remarks are also on point. Calling out people is an art that's sorely missed nowadays in manga, be that by the narrator or another character.
Their interaction feels like a manzai and I'm here for it.
BTW I'm cheering for her, while all his plans go under or something. For him to experience love in a way out of his plans after all this would be very interesting.
