Sachiko Ogasawara

Sachiko Ogasawara is the refined student known as the Rosa Chinensis. Though she loves her sister, Yumi, Sachiko often hides her struggles, which leads to painful misunderstandings between them. A difficult home life and a complicated engagement to her cousin, Suguru, have left her with a deep-seated distrust of men. Behind her stern exterior, she deals with intense personal grief and shifting friendships, eventually finding connection through music and her devotion to those she cares for.
