30-year-old health and physical education love flag

Misaki is a 30 year-old virgin who has a bit of a crush on one of his co-workers, a pretty girl named Amano, but he has no experience and no clue what to do. Fortunately for him, he has an ecchi guardian angel...

Yamada has not had a girlfriend in his entire 30 year life and is still a virgin. He'd had a crush on Tanaka in high school, and to his delighted excitement, when they met at their reunion they began going out together! 

But because Yamada has had 30 years of absolutely no experience with women, he struggles with even the absolutely simplest of things, such as holding hands. What makes it more complicated is that Tanaka is also a shy person who isn’t great at leading him through the process. The couple awkwardly makes their way through the relationship one nervous step at a time.
