I think this is becoming a Japanese series thing... the series are never bad but they aren't amazing too, they're always in the middle,
The main characters were sort of annoying, especially Nozue, he was too obsessed with work and with the fact he was almost 40, that really annoys me.
Togawa, is just like the series I loved it and hated it, he was so hot an so cute, he was totally in love with Nozue, but he was also too much in love, he kinda creep me out when he gave that neck kiss to Nozue while he was sleeping, that was really strange...
The kissing scene was good, I liked the way Nozue's actor didn't closed his eyes during the kiss, it showed the mixed feelings of the character at that moment.
Overall the series wasn't bad as I said before, but that are a lot of things that could have been so much better if they had change some little things in it.
