Feeling alone... doing all the annoying housework... these are the things that come with the freedom of living alone, but Rei doesn't have to deal with this at all! When she comes home, her next-door neighbor Shuichi welcomes her with warm food and a caring smile! The two first met by chance because Rei accidentally walked into Shuichi's apartment, thinking it was hers. It's so nice to come home to someone waiting for you... It's as if they're living together. Rei finds herself gradually falling for Shuichi, as the time they spend together is always warm and happy, except she realizes there's someone in Shuichi's past he still hasn't gotten over yet...!!
