Hoping for Kotooka x Tsukasa endgame. It seems a lot of people are getting annoyed at Kotooka right now, but I think she's the most interesting character. She might be a little pushy with setting het friend up with a guy, but it seems to be a way of coping with her own feelings. Maybe she thinks she can move on if Tsukasa is taken. They are only in middle school so their actions aren't out of the ordinary.
This x 1000. Kotooka knows what's up and I think people getting annoyed with her aren't giving her enough credit. Yeah, she's pushing the girl she likes to be with someone else, but Tsukasa is going on a date with a guy just to forget about who she likes--instead of just acknowledging that she isn't interested and letting him know that. They're young and doing stupid things.
I can see how Kotooka's high energy would put people off, but man, it just makes it that much better when she's all gloomy and deep. That was what really kept me here, the introduction to her feelings for Tsukasa. I thought this was just going to be one of those linear triangles where Tsukasa likes Nadeshiko, Nadeshiko likes Kotooka, and Kotooka likes some random dude. But then it truly became a triangle in such an interesting way, going back to that meeting on the train and seeing that Kotooka was part of it from the beginning. She's unexpectedly deep.
Just, man, I love this girl. Ahaha.
