Thananya is an accounting professor at a university in Bangkok. Her parents who live in the province of Pitsanoolok want her to come home and marry a guy that she's never met. Thananya, of course, doesn't want to leave her work and life in Bangkok, and accidentally blurts out that she already has a boyfriend to make her parents leave her alone. However, her parents want to come to Bangkok to meet this so-called boyfriend. So her parents, sister, grandmother, and the family maid were on their way to Bangkok. Thananya and her friend, Pleun, scheme up a plan to hire someone to pose as her boyfriend for 3 days.
Gon is an aspiring young artist who has dreams of becoming a famous artist in Italy. He was orphaned since he was a kid and was raised by monks. He is friends with Pleun, so when Thananya needed someone to pose as her boyfriend, Pleun suggests Gon. Gon is at first hesitant, but takes the job because he wants the money to go to Italy. He was also pushed to take the job by his girlfriend, Jikgee. The agreement was that Gon would pose as Thananya's boyfriend for 3 days in exchange for 30,000 baht.
When Thananya's family arrives, many challenges ensue as the couple has to pretend to be lovers and know each other. Thananya's father starts to give into liking Gon after he gets stabbed while trying to fight thugs who steal Thananya's father's wallet. Realizing that Gon is in fact a good person, Thananya's father decides that the two should get married. This was more than what the original agreement was for, so the monetary compensation increases to 100,000 baht, and Gon and Thananya play along and get married.
