Let's forget about the main couple and focus on the main question. Squirrel-chan is on the beach? The cliché of defending the girl can be interesting if the Chief is the fighter. It's time to show off your cute masculinity.
wth is wrong with some people, how are they talking about ntr in the series, she's clearly there with the fluffy friend and squirrel chan, we even have the chief there.
Mutou needs to hang out with quality men like Chief and learn the ways of a master. Chief is hardworking, kind, and responsible (a good owner of a cute puppy)? Sheesh. Be a delicious man and women will pay attention.
Seriously though, the people someone spends time with tells a lot about that person.
Yes, be more surprised that it's his girlfriend and not someone who looks exactly like her, that makes complete sense. Anyway, Chief be meeting bakery girl, and Mutou is gonna get his hands on that spoiled chick ain't he.
It's wild that there are people who genuinely think this constitutes "NTR bait". God forbid she has any sort of social life outside of her boyfriend. Perhaps she should retire to the church and pray to the lord whenever he's not around to supervise her?
