The 12-episode drama will air once a week on Thursday nights, and it’s an omnibus series about four different couples living together in one apartment complex. Oh Jung-se (Plus Nine Boys) and Ryu Hyun-kyung (Tasty Life) play the main couple in their 30s, who’ve been living together for two years. Oh Jung-se’s character is a voice actor, and Ryu Hyun-kyung plays a reviewer who runs a blog. They’re an average 30-something couple and they simply chose to live together instead of getting married. Choi Yeo-jin (Valid Love) and singer Jung Joon-young (1 Night 2 Days, Today’s Love) play a couple that’s twelve years apart in age. She’s a penny-pincher who basically supports her younger boyfriend, and he’s a musician who carries a guitar but doesn’t know how to play it. They’ve been living together for a year, and though they fight like cats and dogs, they’re always quick to make up. Ha Eun-seol (Yoo-na’s Street) and model Park Jong-hwan play a 20-something couple that just moved in together. She’s the type of woman who doesn’t want her boyfriend to know that she isn’t the perfect embodiment of femininity, and works tirelessly to keep up the illusion. Lee Jae-joon (Dating Agency Cyrano, Night Flight) plays a loner who prefers to stay at home, but is forced to get a roommate for financial reasons. He doesn’t even want to exchange unnecessary small talk with the guy, and thus seeks out a foreigner who can’t speak Korean very well. Idol Takuya plays the new roommate, a young man from Japan who’s on a trip around the world. Takyua thinks it a shame that Lee Jae-joon is wasting his youth as a homebody, and begins to draw him out into the world
