Yoshihara Yuki’s popular manga include: Chocolate Girl and Chou yo, Hana yo.
She is a josei mangaka and her works are usually published in Petit Comic. The stories that I have read so far focus on college/career women… no high school relationships. Her works definitely have more smut and adult situations compared to Yamada Komomo’s. I like them though, and they are pretty hilarious at times. She does a great job with the characters’ facial expressions.🙂
