As a 24-year-old woman, Ogata Makoto doesn't like to show her true self or draw attention to herself in her private life or when she is at work. This is because she doesn't want to be disliked. One night, Ogata Makoto had an accident. The accident causes her to lose the memory of herself. She finds a male ring in her bag, but she doesn't remember who she was going to give the ring to. Soon, three men appear in front of Ogata Makoto, and the ring fits perfectly on all three of them. One of them proclaims himself as her ex-lover, one man claims to be her only male friend, and the other man claims to be her man of fate. Each of them has their own lies.
