Kashiwagi Kokoro (Suzuka Ouji) is a university student who has just started dating Kamijo Sayo (Tanabe Momoko). One day, as if to ruin his happy life, his ex-girlfriend Omori Ringo (Konishi Sakurako) barges in and starts living in his house. Perhaps due to unresolved feelings from being dumped by her in the past, Kokoro does not chase Ringo away and lets her stay at his place without letting Sayo know. This leads to a love triangle between the three when Sayo starts noticing the presence of Ringo. (Source: Irozuku Subs)
