I don't wanna validate cheating by blaming it on Nanase like a lot of people does. It's perfectly fine to focus on your dreams and prioritize it, but don't get yourself a girlfriend if you have this in mind. Of course, any sane girlfriend will support you, but the problem is, "time", you have to perfectly manage your life and your love life. What's happening here is, Nanase don't have much time to look out for her girlfriend getting bite by a wolf and has no way of knowing unless she looks closely. Yuni seems to find the comfort from Fuuka, but I guess I want to know more of Fuuka's pov. To what her real intentions are, and her feelings for Yuni.
