Mitsu (Haru) works at an eye clinic. Ryota (Masahiro Higashide) visits the eye clinic as a patient and asks her out on a date. He is gentle, responsible and places Mitsu first. Ryota seems like a perfect man to marry. Mitsu though still has her first love in her mind. Her first love is Koki (Nobuyuki Suzuki). He moved out without telling her goodbye.
Mitsu still remembers the fortune-teller from her middle school student days. The fortune-teller told her “you should marry the man whom you love the second time.” Mitsu decides to marry Ryota. They marry with congratulations from everyone around them, but, one day, Mitsu meets Koki again.
