You have to be some kind of genius to have your protag have some introspection and determination to resolve conflict while stile committing to be a degenerate. And that final curve ball, I kneel 🙌
As always, unlike Gotou, Agawa is nowhere close to be honest with her feelings. Instead of addressing them, she goes for distraction and (male) validation. To anyone with any self-awareness, it would be clear that she's bummed that her chemistry with Goto seems gone, plus she's hurt after seeing him forming his own harem when he was her very own promising stallion or what.
But here she goes, trying girls now. Even for somewhat clumsy reasons, a break from meaningless sex would have been healthy but she switched to tick another box. I get that's the whole premise but you have to be a retarted masochist to fall in love for someone that has no interest in her emotional wellbeing, only her immediate comfort.
