Is she really a cannon lesbian? I'm pretty sure her brother had mentioned that she has brought boyfriends home before, though I may not remember correctly.
She is! When Nozomi asked her if she and Shino's brother (the dead one lol) had anything going on between them, Ritsuko said that Nozomi didn't need to worry because she and Shino's bro had the same interest in girls.
Ah, yeah, I do remember something like that, now that you mention it. I guess the supposed boyfriends weren't actually boyfriends then. (Or maybe there weren't any boyfriends to begin with and it was just me who thought that her brother said something of the sort lol)
Yo, you guys know which chapters these are? I don't remember this at all. Maybe it's time for me to re-read everything.
