Masaaki, who started an asset management company, has been getting his business on track since marrying Yoko (Izawa Chinatsu), who grew up in a wealthy family. The business had previously struggled, but thanks to his father-in-law's trust, he was able to get work and increase his customer base. The couple lived a happy family life until one day, Yoko was kidnapped. Masaaki received a call from an email and rushed to the scene, where he found his ex-girlfriend, Sae, holding Yoko captive with a group of unknown men.
