Second 20's

Ha No-ra once dreamed of becoming a dancer, but she unexpectedly became pregnant at age 19 and had to quit school and get married. For the next two decades, her life revolved around being a housewife and mother. Now 38 years old and on the brink of divorce, No-ra is diagnosed with terminal pancreatic cancer and given a six-month prognosis. So she decides to go back to school and experience college life for the first time. Among the incoming freshmen are her own 20-year-old son Kim Min-soo and his girlfriend Oh Hye-mi, who are horrified to have No-ra as their classmate. Unbeknownst to No-ra, her intellectual snob husband Kim Woo-chul recently accepted a job teaching psychology at the same university, and her prickly theater arts professor turns out to be Cha Hyun-seok, who had a crush on No-ra in high school. [About:]'Second 20's' is a 2015 South Korean television series starring Choi Ji-woo, Lee Sang-yoon, Choi Won-young, Kim Min-jae, and Son Na-eun. It aired on tvN from August 28 to October 17, 2015 on Fridays and Saturdays at 20:30 for 16 episodes.[Source: Wikipedia]
