I'm gonna say it:
Because of the similar hairstyle, I hear Seto's voice as Oozora Subaru, in my head.
Oh no I'm hearing it too now that you say it
Gonna try that on reread lol.
It's understandable that some wouldn't like this, this is more ecchi then it is yuri, but it is also yuri and I think it's a lot fun, also the art is quite superb in general. I don't really get what Senpai sees in Past-kouhai, maybe she picked up on at that she looks at her with lusty eyes rather then with admiring eyes and she liked that?
Considering that something like Why Are You Here Teacher?! was turned into an anime(I have yet to watch it tho), it's a bit fun to imagine that this could too, it wouldn't be too far off from fan service yuri anime like Sakura Kiss or Citrus, just give it to a studio that knows the ecchi genera. Now that we are further out in the series, I'm actually enjoying the rest of the characters from the film club more and more. In an anime maybe it would have been better to introduce them quicker so there is more characters to bounce around.
