The narrative follows Sun Tae-Hyeong, portrayed by Bae In-Hyuk, an assistant photographer who values his personal space and independence while harboring unexpressed emotional pain beneath a carefree exterior. Woo Hyun-Jin, played by Roh Jeong-Eui, is a job seeker striving to achieve a stable and ordinary daily life. Although connected as in-laws, Tae-Hyeong and Hyun-Jin experience persistent friction and bicker frequently.

Their lives undergo a dramatic shift when Tae-Hyeong's older brother and Hyun-Jin's older sister perish in an accident, leaving behind their 20-month-old child. To care for their nephew, Tae-Hyeong and Hyun-Jin begin living together. Through managing complex parenting challenges, they resolve long-standing mutual misunderstandings and gradually transform their relationship.
