Akio and Umi are roommates but never talked to each other until one day Umi comes home dead drunk and bumps into Akio. The worst first impression. They start to have a close relationship mainly because Umi develops some feelings towards Akio, who don't feel anything for anyone.
A really beautiful story about two men who fall in love without even notice. The art is amazing and the plot is interesting.
