I had a childhood friend named Hiyori whom I hated. After failing to get into college and find a job, I returned to my parents' house for the first time in 10 years. One day, I happened to meet that troublesome Hiyori again... Hiyori, who had become a flight attendant, was beautiful and truly out of my league. And before I knew it, I was captivated by her, and my body became unable to live without her... even though I hated her... A drama about ejaculation control and training in which a virgin childhood friend is turned into a submissive pet for personal use.
