IT employee and socially awkward Nam Se-hee (Lee Min-ki) marries homeless writer Yoon Ji-ho (Jung So-min) by signing a contract of two years. Both parties agree to the terms and conditions of being just landlord and tenant. They plan to share the flat based on common goals and values, but without any feelings involved. Things don’t go as planned since the housemates fall prey to their personal trauma, social expectations and familial interventions. The movie also follows the lives of Ji-Ho and Naam Se-hee’s friends and their different perspectives on love and marriage.
