I never want to go through that again." Completely spiteful, Kazuya uses a certain method to date a girl. He goes to their meeting place and suddenly hears, "You're Kazuya-kun, right?" A beautiful girl brushing her long, black hair behind her ear was there, smiling at him. Her name was Mizuhara Chizuru. Something real is born after just a single rental! A reckless rom-com filled with love and excitement is about to begin!
