The story progresses through several distinct structural phases:
- The Instigation: Mi-ran overhears Kang-ho complaining bitterly about women to Won-jun and vows to punish him, taking a position at Gilmu Law Firm to gather evidence.
- The Contract: Kang-ho is accidentally caught in a compromised position that leads the press to report he is gay. Won-jun orchestrates a fake-dating scheme with Mi-ran to clear Kang-ho's image.
- The Shift: During martial arts training for an upcoming blockbuster, Kang-ho kisses Mi-ran to test his panic attacks and discovers she is the only woman who does not trigger his trauma. They fall genuinely in love.
- The Crisis & Finale: An envious acquaintance leaks Mi-ran's past dating history (over 100 ex-boyfriends whom she dated and tested). The media labels her a predatory gold-digger, threatening Kang-ho's endorsements and career. Mi-ran breaks up with him to protect his reputation.
- The Resolution: Numerous women—including clients, acquaintances, and ordinary citizens whom Mi-ran had saved from abusers and cheats—flood online forums to defend her honor. With her reputation redeemed and the public's hypocritical double standards exposed, Kang-ho and Mi-ran joyfully reunite on entirely equal footing, while Won-jun and Na-eun cement their own romance.
