Second 20s

Ha No-ra is a 38-year-old housewife who has dedicated her entire adult life to being a devoted mother and wife. After being diagnosed with a terminal illness—which later turns out to be a misdiagnosis—she decides to reclaim the youth she sacrificed by enrolling in college. She enters the same university as her 19-year-old son, Min-soo, and her husband, a conceited psychology professor named Kim Woo-chul, who has long looked down on her for her lack of education. As No-ra navigates the challenges of campus life, she encounters Cha Hyun-seok, a successful theater director and professor who was her high school classmate and secret admirer. Through her journey of rediscovering her dreams, friendships, and self-worth, No-ra begins to break free from the constraints of her marriage and finds the courage to live her life for herself, ultimately transforming her perspective on what it means to be in one's twenties.
