I just found this really good Korean movie that I needed to share.
Min-soo (KIM), a gay man, and Hyo-jin (RYOO), a lesbian, both decided to get married. Not to their respective partners… but to each other. Their devious plan works perfectly. While secretly living with their partners, who move in next door, they appear to the outside world as a “normal” couple. They enjoy all the benefits afforded to heterosexual couples and also are able to ward off the curiosity of parents and any others who might disapprove of their lifestyle. However, Min-soo’s intrusive and incredulous parents begin to get a bit too involved with his life, threatening his scheme.
You can find the movie with English subtitles here.
