Airi Meguro works as an office lady. When she was a child, she thought that when she grew up, she would naturally fall in love and get married, but before she knew it, she was 29 years old, single, and without a boyfriend. I panicked and tried to register on a matchmaking site, but I couldn't find anyone, and my frustration only grew more and more... Hada, who I thought were just good juniors, said to me, ``I'm the one who's the one.'' "Is it no good?" and suddenly approaches...!? A life-sized office love story between a cool junior who is an expert in love (?) and an older woman who is timid when it comes to love!
