Ritsu was rescued from a fire at her apartment by Sagimori, a professor from her university. With no family and no place to go, she accepted his offer to spend the night. She was warned to avoid one room, but she ended up discovering Sagimori's secret. Ritsu mistakenly believed it related to his missing fiancé, who had disappeared on their wedding day. Despite his assurance that he is not interested in real women, Sagimori proposed a contract marriage.
