I liked the first few chapters but the uncalled mind games on Kyouko, the other messed up couple intervening, and Miku's BS are making this unreadable. Kyouko isn't any better as she shouldn't go along with everything Miku's giving her.
Surely, if the conclusion is to have Kyouko and Miku together, there should be character development from both sides. While Kyouko seems to gradually grow more conscious of Miku, it's done in a very unhealthy way (making Kyouko be jealous and have her imagine NTR scenarios). There's no development for Miku whatsoever. Her only role seems to be to play innocent (at times) and nasty mind games on Kyouko and now, seemingly, rush her decision, like tf? But it doesn't seem that there's any plans to make Miku change in a way that would make her more suitable for Kyouko or make her realize all the BS she's been pulling.
