This was one of my first BLs (well, more specifically Yaoi as it's explicit), and it really hooked me in with the cover art. It's still one of my favourite BL's.
Needless to say, the gorgeous art is an instant 10/10.
Story: kind of the classic opposites attract story. I quite like the concept.
Ogata (stoic man) and Saya (smiley man)'s relationship develop well, and there are hot moments as well as cute moments. Personally, the development feels a bit too quick to me, but that's probably just in real time, as in the story they develop it over a longer amount of time. Well, compared to most Yaois, this is one of the better paced ones. There is drama in the middle of the story where Ogata couldn't bring himself to have sex with Saya, and this damages their relationship, but they resolve it at the end. It's a happy ending story, and I like the ending.
The main characters have lovable personalities, and realistic fears to overcome. There are nearly no extra characters, and the ones that do appear are a push to the main characters' decisions. The story focuses on just the two of them, which I like.
Definitely recommend it.
