The initial premise (of Mayuki getting Akira to love her) comes back and we have a better idea of how high the hurdle Mayuki has to climb.
A bad end would be Mayuki getting demotivated and applying for a different school. Really depends on Akira LOL.
Since Akira likes Rin for general appearance reasons, technically any “mature lady” would do for her. So Mayuki’s lucky that Rin happens to be the way she is.
I generally like characters that go from “zero to hero” hence why I like Mayuki, otherwise her first impression with Akira would be too overbearing Stan.
I’m not sure how much work Akira has done to get to where she’s at, but she’s definitely going to need emotional growth. I do like “villainess” characters which is where Akira sits in my mind right now, but that like also depends on her character growth from a “perfect high horse jock” to someone more flexible minded.
