Asumi's gonna top her. I just know it.
I do wonder what Asumi's thoughts are on her relationship with Mai. She's clearly into her on a sexual level, but she's into most women on a sexual level so that doesn't tell us much about what she wants their relationship to be. Mai obviously wants them to be a couple, but Asumi has never actually indicated that she wants that with Mai. She did all this just to reconnect with her and apologize. She might just be thinking of her as a friend, and only went along with the kiss so Mai could "make up" for her last attempt. Maybe she wants them to be sefure, like her and Nanao are. Maybe she's not thinking about the future at all and is just letting her horniness take control. Who knows.
My point is, Mai and Asumi seem to have different ideas for they want out of their relationship, and I'd like to see when those expectations start to clash. Hopefully soon.
