Irene, who disguised herself as an ordinary flower shop girl in Gray Harbor Town, has only twenty-eight days before she will awaken into a complete vampire - losing her memory and herself. Just as she was looking for a way to suppress her, Victor, Silver Cross' youngest S-class hunter, followed her. She originally planned to use him to get the truth about her mother's death, but she approached this cold hunter step by step through temptation and disguise. When he discovered that the organization was the real murderer - he chose to betray the whole world and stay by her side. But the second betrayal came faster: she found the blood trail on him that was tracking her, and heard the command to "capture alive." The countdown to awakening and the collapse of trust are approaching at the same time, and she must make a choice: become a monster, or become herself.
