Meet the In-Laws (2012) on Netflix

Hyun-Joon (Song Sae-Byeok) is a comic book artist from the Jeolla-do region, now working in the capital city of Seoul. One day he meets Da-Hong (Lee Si-Young), a fan of his who is from the port city of Pusan. The couple's relationship has progressed where they are now thinking of marriage. The only problem is Da-Hong's father (Baek Yoon-Sik) has a severe prejudice of people from the Jeolla-do region. When Da-Hong's father was younger he was a professional baseball pitcher. He was then beaned in the eye by a pitcher which ended his baseball career. The pitcher was from the Jeolla-do region. Making the couple's possible marriage even more tricky, Hyun-Joon's father (Kim Eung-Soo) wants his son to marry a local girl from the Jeolla-do region. The couple then comes up with an idea. Hyun-Joon will go to Da-Hong's home and tell a "small" white lie about his background - that he is a native of Seoul. Now, Hyun-Joon must lose his regional Jeolla-do dialect and also be able to lie to his possible future in-laws. Meanwhile, Hyun-Joon's father sends his assistant Dae-Sik (Park Cheol-Min) to follow Hyun-Joon. Can the couple ever survive?
