Alternate Title

Otona Nya Koi no Shikata ga Wakranee!


Mio Sudo is an office lady who hasn’t had a boyfriend in five years and doesn’t understand love. Shuji is a consultant who hasn’t had a girlfriend in seven years despite being a prime candidate with his good looks and charm. The two meet at a matchmaking party, but Mio is immediately turned off when Shuji tells her he doesn’t have any interest in women. However, one provocative comment is all it takes to send things in an unexpected direction and sparks begin to fly.
