Otona nya Koi no Shikata ga Wakaranee!

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: The anime will have two versions, each with it's own cast. The "On-Air" version will air on TV, while a "Premium" version, which contains explicit content, will stream on the ComicFesta Anime website
