He's just teasing her and is not the affective type that's all but if you look closely you can see how much he loves her, the proof is she's the first girl where he can be who he reallly is
Erika can look over his acts of cool guy and know how he is, she fell in love with him and how he is, so she doesn't want him to change to someone he isn't
So I think you just didn't understood the couples thought and their for each other
But then... everyone their own opinion
That's all for me ╮(￣▽￣)╭
I wish Erika could have some pride, seriously Kyouya is constantly making her cry and breaking her heart, he's a dick, yet she always returns to him literally begging him to take her back. Honestly she should've moved on from him and found someone else. The only time where I could actually ship them was on the last chapter where he was actually respecting her. （￣へ￣）
