Takuya and Rika are singles who work for a travel agency. One day, their manager announces that someone from their location must become a branch manager at the Alaska location opening the following year.

Takuya receives a call from someone who knows their engagement is a hoax. Their colleague Gonda insists on visiting. Gonda brings Keisuke and Komiya to tag along and they drill Takuya and Rika about their plan to get married.

Rika's mother Ritsu and Takuya's father, Koichi, somehow learn about his son's fake wedding plans. The young man's father takes a flight to Tokyo to visit his son's workplace.

Rika and Takuya announce that they don't plan on getting married. After seeing how close Nao and Takuya are, Rika keeps an emotional distance from him. Ritsu arranges to set Rika up with Osawa, who pays Rika a surprise visit at work.

Nao moves to Tokyo, and Rika spills her frustrations about Takuya's wavering feelings to the newcomer. Nao then calls Takuya to Rika's apartment.

Takuya confessed his love to Rika, but she doesn't understand what he sees in her; Gonda tells Kaori that he wants a serious relationship with marriage in mind, but Kaori has a secret.
