Guilty Pleasures - Ongoing

What can I say? IT'S SO FRUSTRATING, but I want to see the end of it. Like, how can they redeem their characters? Will they really change for the better? I'm still not giving up on this because I want to see the mangaka's take on this setting.

I'm very bothered with the casual sex and the way they treat relationships, but seeing it in a different POV, I'm still hoping that they would learn from all the pain they caused and felt. Honestly, I want to yell at the woman for being so tolerant (or st***d?) but I still haven't given up hope that her character would somehow develop strongly, to make a difference for women in the same mentality.
