Imai Karen has the most stunning looks and has toyed with many men. She works hard as a PR professional for a cosmetics company, and her work and private life are fulfilling, but she has not been able to overcome her past trauma and has told herself that it is pointless to fall in love seriously. One day, at a drinking party with friends, she meets a dull-looking guy named Domae Teito, who is wearing glasses. Karen is turned on by Teito's cunning attacks and does not flinch, so she tries everything she can to win him over, but he does not respond at all.
