Idk what happened with Seyoun and Chanyoung, but I feel like Seyoun liking Myeongin is just a plot device to push Chanyoung to take action. If Chanyoung really is a playgirl, then it's good that blondie moved on (even if Myeongin was the cause). She can finally move on and find herself a new gf (that isn't Myeongin) and be bffs with Jiwon and Myeongin. Tbh she deserves better.
