It's a really interesting story (mostly because of the characters, not really of the storyline) even though it's quite unpopular. We have two fairly different characters. Shizuma had been living a peaceful life with his really likeable girlfriend, until they had broken up. On one morning some days later, Shizuna woke up next to a stranger, Minato, and it seemed they had... let's say "an interesting night together" in case children are reading this, but Shizuna didn't remember anything.
Shizuna is calm, intelligent and he lives for his work, so Minato, a person with loose morals wasn't very sympathetic to him. Minato knows this, however,
he tries to seduce Shizuna because of a bet, and this is where the problems start.
Exciting, but not too complicated. It doesn't have many hot scenes (there were two during 5 chapters) (and they are just "hot scenes", nothing more), but at least it has some.
I have never seen any yaoi with this much character development (or any, for that matter), so it was a pleasant surprise.
There are some colored pages, so we can imagine the characters better.
At the beginning, it's a liiiitle bit boring. But it becomes more and more entertaining.
