the first couple are a sempai/kohai at work. Sempai-san was dumped harshly by his last love, so he doesn't believe in love anymore. Kohai-san confesses and they fall in love <3 Second couple went to high school together. Uke-chan was a gloomy guy, but he loved Seme-kun so much that he changed his personality and tracked him down six months later. Uke-chan is pushy but he convinces Seme-kun to give him a chance. Third couple, two old friends ran into each other after three years. Uke-san had an unrequited love for Seme-kun, but he didn't want to ruin the friendship, so he never contacted Seme-kun again. But now they run into each other again?! and Seme-kun wants to know why uke-chan ran away three years ago.
