Intro. Haru is a seven-year-old Japanese girl, daughter of an important family, although the result of infidelity. Her father recognized her, but she never received the same treatment as her legitimate siblings, Akano and Kaede. His strict and ruthless grandmother controls his life, and Haru cannot disobey her or any other member with legitimate children. Since she was little, she learned to follow orders without protesting and not to cry when faced with punishment, becoming accustomed to contempt and mistreatment. She is extremely shy and quiet; He speaks little and with a soft voice, measuring each word. Her world is limited to obeying, taking care of her siblings, lifting them, dressing them, feeding them and making sure they don't get into trouble, because any failure falls on her. Haru maintains his health only as much as necessary, without indulging in luxuries. Although she appears fragile, her silent strength comes from enduring rejection and fulfilling her obligations without expecting affection or recognition, living to serve and protect like a servant.
