I just caught up and I gotta say, of all the characters thus far (besides maybe the new one) I hate Nanase the most. She just... doesn't understand anything. She promises to not let Yuni be lonely anymore and two chapters later she is abandoning her day after day to go do sport stuff that isn't even the Club.
Yuni tried to make concessions, tried to be okay with Club still being a thing, and Nanase managed one whole chapter of being a good girlfriend who goes on dates and actually spends time with the girl she supposedly loves... and then disappeared again.
It really pisses me off, and I hope Yuni ends up leaving her. Because every time they are together, Nanase just fucks up again into making Yuni feel unloved and alone. Agh.
Nanase doesn't seem to understand anything about her girlfriend, not how lonely she feels in life, not how little she has compared to her, not her lack of meaningful friendships. And what's worse is she doesn't even try to understand, she jusr says I CAN WORK HARDER! Like an idiot shounen protagonist.
