I'm still a but confused at the ending of chap 8, silver hair girl says he more honest with yourself, does main character have feelings left for the man and that's why grabbed silver's arm or was she just irriated
From what I remember (I'm on my phone, it's too inconvenient to reread, my bad if I forget anything TTvTT):
As much as MC feels attracted to this new girl (and how her ex is an obvious douchebag), we can't deny that she did date him for x amount of time, she wouldn't go out with him if she didn't at least like him a bit. Seems like the relationship wasn't ideal tho, and that she's been putting up with his flaws/shortcomings for quite a bit, and his unfaithfulness is the obvious straw that broke the camel's back (as in, he could have been great, but cheating is still ofc a dealbreaker lol). It's good to see that she has self respect/knows she deserves better however, and recognises that he's a fucking jerk, hence doesn't plan on continuing dating him.
I suppose what the short-haired girl meant is that as rational as MC is about dealing with his bullshit, that she suspects that it isn't completely over on MC's side, and that she needs to properly deal with/respond to that.
