A gay man, Min Soo and a lesbian, Hyo Jin are both promising doctors at a general hospital. The colleagues agree to marry so Hyo Jin can legally adopt a child with her lover of ten years Seo Yeong, and Min Soo can please his parents while maintaining his closeted lifestyle. While secretly living with their respective partners, who move in next door, Min Soo and Hyo Jin appear to be a happy, "normal" couple. They enjoy all the benefits afforded to heterosexual couples and are also able to ward off public scrutiny and parental disapproval. However, Min Soo's intrusive parents begin to get a bit too involved with the couple's life, threatening their scheme.
