“My son has been kidnapped!”——Private Banker Anno Koichi (played by Karasawa Tomeaki) received a request for help from Tenguji Saori (played by Tsuchiya Anna), the eldest daughter of Tenguji Temple.After receiving the news, Anno, together with his assistants Iida Kumiko (played by Suzuki Honami) and Miko Shibasu (played by Uesugi Hiiragi), immediately went to Saori's mother Tentenguji Aina Group Vice President Mikoto Tentenguji (played by Mari Natsuki)around.Yes, the person who kidnapped Saori's son Tenguji Kaito (Kawahara Eito) was Mikoto.

Mikoto adopted her grandson Kaito as an adopted son in order to solve the inheritance problem, but the real purpose was to educate Kaito thoroughly by Mikoto's side and train him as an heir.There, Anno accepted Mikoto's commission. In order to establish this adopted son relationship, he needed the consent of Saori and Saori's husband Tentenguji Hiroki (played by Tamaki Hiroshi).

Saori, who couldn't hold her head up in front of Mikoto, asked Hiroki to refuse clearly.As a director of the Tenguji Aina Group, Hiroki believes in what Mikoto once said: "I'm looking forward to you". He said that if it were him, he could take back Kaito...In fact, Hiroki obeyed Mikoto's words and was ridiculed by his subordinates as the "dog% of the Tenguji family".As a result, instead of refusing, Hiroki fell into the crisis of having Kaito taken away from him.

One day, Hiroki finally clearly rejected Mikoto's adoption of a child, and Mikoto unexpectedly responded calmly...Later, Hiroki was demoted in the name of promotion.Anno appears in front of Hiroki….Soon, Mikoto's terrifying plan against Hiroki will be revealed──!
