La ligne qui nous sépare

Twenty-four-year-old job seeker Im Yu-Ha returns to her parents' house in tears after a series of job rejections following her college graduation. There, she encounters Ji Min-Gyu, the youngest son of the homeowners and the black sheep of the family. At their first meeting, he rudely asks, "Are you the new helper who moved in today?" and behaves disrespectfully. Under the same roof with the immature young master she never wanted to get involved with, ro...mance? Absolutely not! Let's keep the line we should never cross between you and me.
