It's been 10 years since I married the man my parents wanted.Maki has always been a good girl, but when she was in school, she received a phone call from Ryoko, who was enjoying her girly youth, and her life was at a turning point...She didn't even know a man when she was in ○ school.And she reunites with Ryoko for the first time in more than ten years, remembering sweet and sour memories and layering each other's skin.The desires of the two people who caught fire again sought each other's fists just like those days.
