I had a childhood friend named Hikari whom I hated. One day when I returned to my parents' house after 10 years after failing to go to college or get a job, I accidentally met Hikari again... The Hinoha, which had become CA, was beautiful, and it was indeed a flower of Takamine. And before I knew it, I was captivated by Hikari, and my body became a body that could not live without Hikari... I should have hated it... An ejaculation management training drama that turns a childhood friend, a chaste man, into his own obedient pet.
