I've read until chapter 20-ish, and I'm... still not sure how to feel about this. I like the art: it's not your typical shoujo art, and some may drop this because of that like they do Yandere Kanojo, but for me it's not a problem at all (there are some characters who look like the characters in YK, but that's just a minor problem for me). The problem is... well, the story. Or should I say, the premise. I've read many manga with similar premises (just look at the categories), and boy, was that a train wreck. Some of them end so unsatisfying, most of them end so bad they make me question all my decisions in life, and only one or two live up to my expectation. This kind of premises just doesn't bode well with me, because at this point it's like some sort of gambling where I lost more often than not. It makes me expect things, makes me expect more, then drop those expectation ten meters below the ground, drag it horizontally to the end of the world, and leave it there to rot. And if you still cannot guess, it hurts. A lot.
Anyway, that's just me and my bad experiences with this kind of premises. I'm waiting for the mangaka to finish it. When that done, I'll read the final chapter conclusion: if I like it, I'll continue catching up chapters, but if I don't, well, at least I only have a memory where all is rainbow and flower petals. Before that, I'm dropping it. Yes, I know I'm a coward. Trauma seriously sucks.
Here's some tips from me. Try some first chapters. If you like it (like me), continue some more, and if after that you still like it and do not have any bad experience shadowing your mind when you read it (unlike me), then welcome to the train. I wish you a wonderful journey, and may we meet again at the end of it.
