Yep. But... I think some real life couples are somewhat like that... The guy cheats on her and sometimes the girl could not say anything... And as soon as the guy apologises or acts a little nicer, she just forgives him. She could just find a new man for herself. Or, just never like anyone... Or make him feel pain... Physically and mentally and make him beg for mercy!!! ... Just kidding. I come in peace. The one about her kissing another man in front of him is probably the best suggestion... Although I have the slight feeling that it will just make him angry and they'll break up just like that and then the end.
Because if he's willing to hurt her then, like that, won't he hurt her more soon? And intentionally at that, for play? Did he even consider the other girl's feelings after he was reunited with the girl?
last story gil need to find another boy and kiss him
