I mean, technically CF didn't do something THAT bad and with the manager girl, it was an accident. Is not like he is jumping into a romantic relationship with them.
I look forward more to the elementary school bullying arc. I suspect the manga will only last that long.
If I remember correctly the story becomes quite similar to what Makeine does - every girl who ‘cursed’ him becomes a losing heroine. I really hope Goddess senpai wins though
