Worked as a caregiver in Japan to escape sexual assault from foster parents in his hometown. He was living a calm life, but one day he appeared in front of a hated foster parent. It was a crime without a way to do it like before, but it was repelled by the old man who was in charge of long-term care, and the old man became a benefactor for the old man. Taking this opportunity, he began to want to provide loving care to the old man instead of work, and started giving back to the old man using his young and innocent body.
