In my opinion the most accurate way to describe this show so far is "gentle".
Unlike most BL show, right from the first 10 minutes of the first episode you can tell who are the 3 main couples.
2 of the couples are obviously gay characters from their immediate chemistry, you could almost see them undress each other in their minds lol.
Since the plot is moving so fast right from the get go, there are several plot holes that i hope will be filled later on.
The music, vibe and editing are all "gentle" and slow, maybe a little bit more realistic then most bl shows.
So far it's pretty good ^_^.
To tell the truth though, it feels more like a 5 episodes series then a 13 episodes one..
