This work didn't impress me at all. There are many reasons, I'll just point out the most annoying. There's too much blabbering, explaining, repeating the same things over and over again, like about characters' relationship when they were kids - that pissed me off. I'm not retarded so you don't have to explain with details how the characters past relationship looked like in every single chapter. Once is enough, really, have mercy.
In comparison the action takes place in a half of the space here, disproportion between unnecessary, repetitive blabbering and doing something is just too huge. And characters aren't talkative at all! They are stiff, poker-faced (they always have the same facial expression) and in addition they almost don't talk with each other. Seems like fun? Hell no. Only in the end they have a proper conversation. So things happen often inside their heads and it's not the type of interesting inner dialogue, full of important questions, it's always the same thing: we were such good friends, I want him to fuck me. I was bored to the core.
Mangaka didn't even bother to explain why they fell in love or still love one another, cause I don't buy something so vague as "we were close when we were kids" for a reason behind it. Sex wasn't hot either, it was dull and mechanical. There was no chemistry. In the end I didn't feel anything for characters, I didn't care about them and just wanted this story to end as quickly as possible. Enough bragging. I expected something better, especially after checking the rating for this work. The whole manga is average at best and could be compressed easily to a one shot. I didn't like it.
