Okay so cheating is justified for him if he wants to make his lover jealous.... He gets mad because his lovers reaction was calm. Like who blames him for thinking it was inevitable that he would end up cheating. The blonde dude is so childish and doesnt deserve him.
I just want the cheating part to actually be the main reason of anger for once.
I love this senseis work. The artwork is beautiful also the stories i love mic and neo manga too. Senseis work has the right amount of emotion not too heavy or light and good story.
