“I know a lot of good things about you” “My ex-girlfriend is my love coach!” Yuzuki Manami is a beautiful, salt-of-the-earth girl whom everyone admired in her high school days. I, Hajime Kinugasa, am supposed to be the ex-boyfriend she loved ……. We once had a secret relationship of “fake lovers.” Now that it’s long since dissolved, what awaits us as sophomores in college is… “Why are you here?” It was an awkward reunion on a chat app. I confessed my one-sided love for Yuka Shichino, a friend of mine at the same university. “I know you better than anyone else. Manami’s love pointers begin!” A perfect opponent for preliminary practice. But when this one-sided love comes true, what will be the relationship between me and Manami? A slightly mature, coming-of-age romantic comedy that flutters with longing and regret!
