I'm not sure if I missed a chapter or my reading comprehension is terrible, but how exactly is Momoka such a villain to everyone here? She gave up on her love with Rin, dates other people, still feel empty. Rin is pissy over Momoka acting that way, despite as Momoka says, she is not doing anything that terrible and her dating life is her own business. Rin accept a deal to replace the boyfriends, but doesnt actually live up to it and it's a oneway street with Momoka putting in effort, which Rin says later on it always have been that way. Momoka pushes the envelope with the hotel scenario, but at this point Rin is also being unfair. Rin cannot fufill the lovers part, It is a superficial relationship, and Momoka says it's a done deal then. She then starts being FwB with blondie, because they both are trying to find someone to ease the loneliness and superimpose their crushes onto eachother.
Did Momoka get a FwB and ignore her to punish Rin, sure that was definitely a part of it, but also she had the right to be with anyone at that point if she wanted to. Ignoring Rin just meant they were back to the status quo they had earlier which Rin started mind you. There is nothing wrong with Momoka wanting to move on. To me Rin was just incredibly selfish throughout the entire story, and definitely a bigger issue than Momoka, but I assume I got the reading comprehension of a wet noodle, because everyone disagree.
I am not hating on Rin, girl got issues and for obvious reason, but I just feel like pushing all the hate onto Momoka's character is out of place.
Momoka's parents are nice though. Sorry for the rant
