Just finished a reread of the whole thing, so here's a few thoughts.
Asumi is a natural lady killer. Just pure lesbian catnip. The most unbelievable part of this story is that she went all the way to college without getting a girlfriend.
Nanao endgame. That girl fell HARD, and it feels like Asumi could really return the feeling once she has her other business taken care of.
Mai really needs some closure too. Poor girl has pretty much obsessed over her memories of Asumi all these years, hopefully she'll get some release soon.
I want to see Senpai in action at least once, dangit!
I love these two together so much. Doesn't matter what dynamic they're given. Romantic, sisterly, mother/daughter, friends, IRL, whatever. They're just so fun and I'm happy they found each other.
