Keyaki Shoutengai Sakura no Yu  

Tatsumi Azuma is a third-year high school student who excels in communication skills, and Shunpei Eguchi is a tough-looking second-year high school student. One day, while walking to school, Tatsumi accidentally injures Shunpeis hand. Fearful of retaliation, Tatsumi apologizes profusely and promises to make amends for the injury. Shunpei then asks Tatsumi if he would be willing to help out at his family's public bathhouse as a way of making up for it. The two begin their warm friendship from there.
