After graduating, it had been over ten years since the reunion. Sakura was always thinking about her first love, Yuuichi, who she hadn't seen in a long time. And Yuuichi was also thinking about her. Even though they were both married and had families, they couldn't delete their contact information. They were just friends now, but back in school, they couldn't even kiss, let alone hold hands. Now, they're both adults. Yuuichi is drowning in Sakura's mature, beautiful body. Even though she knows it's wrong, Sakura can't stop her first love from reheating.
