"I'll overwrite all the men you've been with until now." Not just my heart, but inside, slowly filling me to the brim...?! Although he'll be leaving three months after she fell for him... Their love becomes a habit. Kotori, who has been searching for love has only been betrayed by men until now. The one who had true feelings for her was the a part-timer at a bar, Taiga. The shop's regulars joke about how well-matched of a couple they are, but does Kotori-san have any reason not to fall in love with him...? "If you're lonely, I'll stay by your side." She stands no chance! A younger man who is skilled at love and conveys his feelings properly... Not falling in love is impossible.
