The romantic comedy centers around two people, both about 30. Mio Sudou is an office lady who has not had a boyfriend in five years and has forgotten what it is like to be in love. Shuji Majima is an overseas insurance consultant who has not had a girlfriend in seven years despite being highly eligible. Mio meets Shuji at a matchmaking party, but finds him revolting as he states, "I'm not into women." However, a provocative comment by Mio takes things in an unexpected direction.
Note: Katsura first serialized the manga digitally under the title Sex Go-Busata, Sotsugyou Shimasu (××ご無沙汰､卒業します｡), buts is also sold in compilation volumes under the title Otona nya Koi no Shikata ga Wakaranee! (大人にゃ恋の仕方がわからねぇ！).
