My name is Ryoji. I'm a 22-year-old fourth-year university student. One day, I suddenly found out that I would have to live with my sister-in-law Arare for 10 days just the two of us. But actually, Arare is a bitter memory for me... During our school days, when we were in the track and field club as seniors and juniors, I fell in love with Arare and confessed... only to be rejected. Even though that happened... to have to live with a woman I once loved, there's no way I can stand it...!
