Ok, so, first of all, until almost the end Tasuku seemed like the seme while Ryota seemed like the uke. For me, that is a negative point, because I like to have that stated clearly.
Another bad thing was that it didn't have much sex nor kisses (I am a total sucker for hot kisses, even more than sex itself). It looked rushed up, but that is not something from this manga in particular, but something I notice Zaou Taishi-sensei has been doing. I dislike it.
The drawings, as always, are awesome (except for the hands, that I really don't like xD).
What I did like, though, was how Ryota got psychologically developed along the story. He went from being a childhood friend stuck in the "we are littel kids playing around" to the attentious lover.
Tasuku wasn't remarkable, but I liked him (at least when he was cold, because after that he totally got like every other uke).
The plot wasn't thaaat great, but it was okay.
Unusual story, at least, right?
PS: I ADORE Katsuyama - I simply love those friends that help!
