The series was based on the Naverwebtoon series Do it one more time (Korean: 한번 더 해요; RR: Hanbon deo haeyo) by Hong Seung-pyo (a.k.a. Miti) and Kim Hye-yeon (a.k.a. Gugu), which was first published online in 2016.[1][4][5]
Choi Ban-do (Son Ho-jun) and Ma Jin-joo (Jang Na-ra) are both 38 years old and married with a little son. Both are struggling through daily lives that leave them exhausted and unhappy. Ban-do is a pharmaceutical salesman who spends his days begging people to buy his medicines, and his evenings either drinking with prospective clients, or helping an arrogant and cruel hospital director, Park Hyun-suk (Im Ji-kyu), hide the fact that he is cheating on his wealthy wife. Jin-joo is a housewife who raises their son while struggling to find meaning in her life, and feels lonely and abandoned by Ban-do. After coming to a breaking point in their relationship, Ban-do and Jin-joo wake up to find themselves as 20-year-old university students. They don't know why they are there or how long they will stay, so they decide to enjoy it and make different choices than they did the first time around. These decisions impact their families and friends.[6]
A pharmaceutical salesman and Ma Jin-joo's husband. He was a Civil Engineering student at Hankook University. However, after he graduated and got married, he started working as a pharmaceutical salesman, begging doctors and directors to buy his products, even willing to spend more money for his clients at bars, do menial jobs, and even be bullied by them. Furthermore, one of his cruel clients pays him to hide his younger nurse mistresses from his wife by using credit cards under his name, with various hotels and motels listed on the bill. One day, feeling exhausted from the cruel treatments from his clients and consistent naggings from Jin-joo, he agrees to his wife's divorce plea, wishing that they had never met each other.
A homemaker and Choi Ban-do's wife for more than 10 years. She was a History student at Hankook University. She used to be germophobic, but after becoming a homemaker, her hygiene deteriorates to the extent of willing to eat her son's food that he can't bite, wearing stained outfits most of the time, and becoming gluttonous, eating at a faster pace than the average person. At first she was happy in her marriage, but after some years she started to feel exhausted and unhappy with her situation of being a homemaker, wishing herself to have a better job and income. She also feels that Ban-do starts abandoning her in term of affection and finances, believing that he is a cheap person. After a misunderstanding one night, she wishes to go back to the time when she had never met him, and files for a divorce while demanding alimony for herself and their son, Seo-jin.
Ban-do's classmate in the civil engineering department. He is a weakling and provides comic relief, but tries to change due to his love for Yoon Bo Reum.
Ban-do's senior at university in the medicine department. In the present, he is the director of a hospital. A very cruel person, he used to use his innocent looks to cheat on his girlfriend — his wife in the present — that he loves only for her family's wealthy background. He continues his old habit of seducing younger and prettier nurses in the present, even using Choi Ban-do's credit card to hide his mistresses at hotels and motels.
Lee Do-yeon as Kim Ye-Rim, girlfriend/wife of Park Hyun-suk in the past/present, who comes from a wealthy family.
