Al never did cheat; he was low-key raped by that 19 y/o bear guy. Nero is by nature flirtatious, and Al knows this (he admitted it himself, saying complacence is good for him). With the secretary guy, Neri shown some degree of maturation by letting him off after just kissing. I think the ending is as happy as we couldget from a slice-of-life-ish manga.
I didn't like that Al and Neri are cheating on each other.
"Kuma to interi" is much better.
