When Kazumi Ichinose was young, he helplessly witnessed his first love's brutal murder. He watched as her lifeless body lay before him, surrounded by a pool of blood, while her killer, Saki Midou, laughed cruelly. Despite Midou's sweet and timid appearance, she had a vicious and dangerous streak that should not be underestimated.
The traumatic event left Kazumi traumatized, causing him to gradually withdraw from society. He found solace in only two friends, one of whom was the bubbly and lively Shino Yotsuya. Yotsuya's persistence and honesty eventually broke through Kazumi's guarded exterior, but their newfound connection came with serious consequences.
Midou's obsession with Kazumi persisted, pushing her to commit a murder years ago. It seemed as though history was destined to repeat itself. She remained fixated on Kazumi, determined to prove that he was hers alone. Anyone who got in her way would face dire consequences - even Kazumi himself might not survive Midou's dangerous manifestation of "love."
