The manga take places at the office, one day the man assigned to go travel outside city to work but man is lazy to go travel and the woman is his friend at the office, so they decides to faking marriage to avoid that job..

I think the genre is comedy romance..

Kekkon Surutte, Hontou Desu Ka? (Are You Really Getting Married?)

Takuya and Rika, who work in the planning department of JTC, a travel agency in the Tokyo metropolitan area, are not very good at socializing, but they lived a fulfilling life alone. However, due to the opening of a branch in Siberia, singles will be dispatched overseas with priority, and Rika who is in trouble asks Takuya for a plan. The two, who have hardly spoken, will get married after only 365 days!?
