Uh... Oh dear. So umm... This is a Yuri with a lot, and I mean a LOT of drama. And damn, you'll feel sorry for Aya. Trust me, it feels like she'll suffer for a while.
The art style is noice. The characters feel human and alive at least.
Overall, it's fine. Just ummm... Not for everyone you could say, especially because of that Smut tag. 7,5/10 for me.
