The story took a long time for me to really get into after the first couple volumes, but then it gets pretty good in the latter half.
The art is great, I love the way the faces/expressions are drawn and portrayed, it really makes it so that you don't even have to read what they say, you know what the characters are thinking.
The main characters are quite deep, while I couldn't really connect to any characters on a personal level, I felt like I could still live through them, their past, and their story.
My enjoyment really wavered throughout, although I did end up finding
myself really liking one of the characters and stuck through it to find out what happens in the end.
Overall I would recommend this for anyone who likes that slice of life/dark romance that has a little ecchi but doesn't go overboard with it. Definitely for 16+ I'd say.
