Shy, naïve Nagi Kitagawa has now been dating his next-door neighbor, the popular yet kind Yu Yamasaki, for over half a year. Though their relationship started by Nagi helping a drunk Yu return home, then sleeping next to him in his bed, they now take things at their own pace, allowing the connection between them to blossom little by little as they spend their everyday lives together. While dating in general is new to Nagi, Yu is overwhelmed by his first feelings of true love. Both boys attend an arts university in Tokyo, although Yu will be graduating soon. Will their love be able to stand the test of time once they no longer go to the same school?
