I was a little excited to read the story after the synopsis (I like BL with an "unhealthy romance" themes), but I found myself utterly bored reading this. I finished the first volume and needless to say, I won't be continuing it. To be fair, I don't know how long this series is intended to be, so things could change later in the story, but this series has lost me as a reader.
The relationship starts with a love at first sight and after that all you see are lovely dovey scenes and sex scenes with characters narrations on nearly every page full of angst. It over-narrates and takes itself too seriously. Too much saying, not enough showing. Then, the involvement of an abusive ex is sooo typical.
Rather than a story, it reads like bits and pieces of someone's emo diary. You may think I'm being overly critical, but the author didn't establish the characters very well. The character motivations are cliched and flimsy.
The uke:
The uke basically "slept around" because his parents died when he was young and he got rejected (romantically) by the caretaker who took him in. Of course, he is the insecure type that has to have an abusive "ex" which causes problems. Ex is in quotes because I don't remember if the story actually clarified their relationship was over before he started going out with the seme.
The seme:
The seme is a misunderstood guy because people judge him by his appearance. He falls in love with the first guy who's somewhat kind to him. Okay, I've read tons of BL with this exact character type, but the problem with this manga is execution. He's so bland.
If you want something that's similar and actually interesting to read, try Itou-san (KURAKA Sui) or something.
