Moegi Mizutani, a dedicated employee, made the move to Tokyo to begin a new chapter. But, one day while returning home, she is unexpectedly hugged from behind by a naked man. Moegi recognizes Haruka, a childhood friend with striking eyes, jet black hair, and a wide grin on his face.
Haruka has always taken pleasure in bothering Moegi and using her as his toy. Before Moegi left for Tokyo, they even shared an intimate moment, causing Moegi to feel self-doubt and uncertainty about their relationship.
Although Moegi longs for a fresh start, Haruka's sudden appearance has caused her to question his intentions.
