Overview
Miki is a rookie erotic novelist who’s never so much as held a woman’s hand. Riko is a die-hard lingerie enthusiast with zero experience with men. Together, these two clueless virgins embark on a literary collaboration—attempting to bring the heat despite the cringe of their inexperience. Miki fully embraces Riko’s obsession with underwear, but when he makes a very hands-on request in the name of research, Riko has to wonder…can you really write what you don’t know?!
