Isn’t it obvious that Agawa-san is trying to confine Gotou to how she wants him, how she enjoys him? She doesn’t want him to have confidence or be cocky. She picks him apart for how he’s acting now. If that doesn’t tell you she’s wrong for him, I don’t know what will. It was fine when he was a simp, chasing only her. To her friend, Gotou was nothing but a boring last option. But now she sees he can get attention from other girls, and he’s gaining confidence. She doesn’t like it.
Agawa-san is clearly jealous, and it is that jealousy that makes her a terrible person. She does not want Gotou to change; she wants him to stay the same. If that means diminishing his confidence, then so be it. She can sleep with whoever she wants, and that isn’t the problem because she knows Gotou will accept her as she is, no questions asked. But he is not allowed the same respect. She cannot accept that Gotou has built confidence by being with other women. As long as he was a simp chasing a girl who would sleep with anyone, it wasn’t an issue. She even tried to destroy his character when she said, "Inukai is handsome… He can get away with things that make you look lame” No matter how you slice it, this bitch is pure evil. In my opinion, Agawa-san is a terrible person.
