Just binged and caught up, gotta say Ranko is by far the better of the 2. Honestly Yuriko is quite selfish thinking that she could become an idol with a relationship ban and just expect the MC to still be in love with her until whenever this ban ends. Then to even suggest a top university in which he has no definitive career path yet seriously he's gotta nut up and realize that Ranko is 100% perfect for him.
Ye I think I'm gonna drop this gals are boring to me especially the pure maiden gal. Idols aren't that much better but I can root for Yuriko more cuz of how determined she is to get all things she wants. Ranko just kinda bleh. All of a sudden she has feelings for the mc when she had multiple chances before the story started. She's pretty all over the place tbh and I just find her boring. It'd be nice if Yuriko won cuz that would actually be interesting given Ranko gets so much attention but this series is pretty generic with it's pacing so it's obvious who's gonna win.
