Really loved Aju and Tsukasa's past arc, though I think it was like 1 chapter longer than it needed to be. But fantastic nonetheless.
It could be because I just breezed through this, but sometimes it feels like the characters say things that only the other person is supposed to get, while having not much context for the readers. Again it could be because I'm sleep deprived, but I found myself being puzzled at many exchanges between the characters.
