Il Jo, an unfortunate illegitimate son, gets abused by his half-brother Seo Jeong In at their father’s funeral and ends up relying on his cousin, Seo Jeong Han. One night, a drunk Jeong Han impulsively kisses Il Jo. Soon after, Il Jo is hospitalized with gallstones, and the prickly Jeong Han pays the 4-million-won surgery bill for him.
Jeong Han then tells him to “pay it back with his body” and proposes a contract that basically states all of Il Jo’s rights belong to him. Il Jo ends up living in Jeong Han’s house and serving him.
Jeong Han, who was always indifferent, slowly finds himself drawn to Il Jo’s innocence and desperate devotion. Their relationship grows deeper, both physically and emotionally, and Jeong Han begins to develop an intense obsession and possessiveness toward him.
