Hardworking Woo Hyun Jin (Roh Jeong Eui) and rebellious Sun Tae Hyung (Bae In Hyuk) wouldn’t normally cross paths, but their lives are forever intertwined when their older siblings decide to get married, making them reluctant in-laws. Unfortunately, their relationship changes dramatically three years later after their siblings die in a car accident, leaving Hyun Jin and Tae Hyung the sudden caretakers of their siblings' toddler son Woo Joo. While Hyun Jin and Tae Hyung initially struggle to get along, they gradually manage to develop an unconventional co-parenting relationship for the sake of their nephew. But the more time they spend together, Hyun Jin and Tae Hyung realize that their relationship might change yet again – if they can figure out how to navigate a fledgling romance while taking care of a kid.
