Yancha na Kare to Hajimete no Koto

Rino, a young editor of the fashion magazine "Lily," is rescued by Suzu, a former delinquent and childhood friend, when she is entangled with a stranger on her way home. A bit nervous at Suzu's calm demeanor, but worried about her work, Rino asks Suzu to help her out. The job is a "sex feature" project...! A tender love story with a single-minded, mischievous boy, and a whole lot of hardship!
