I wouldnt have liked her either. Imagine someone produces a product that keeps you from going insane. And they wont sell it to you. They will only give it to you if you are going to date them. Imagine. Nasty. He didnt abuse her nor disrespect her while they were "dating". He just ignored her while she forced her obsessive feelings on him. And now she changed and seems pleasant to be around. Its no wonder that he is interested.
I feel like it was more that she was acting differently and was showing a different side to herself. Little does he know ot an entirely different person
so the ML started to get interested on her when she started to uninterested and breakup with him? haha there are really guys like that ╥﹏╥
