Living as his children's classmate, Dae-young discovers painful truths he missed as a father—such as Shi-woo being bullied and Shi-ah working secret part-time jobs. He uses his new position to protect them and becomes a "friend" to his own family, gaining a deeper understanding of his wife, Jung Da-jung (Kim Ha-neul), and their failed communication.

However, unlike typical time-travel tropes where the protagonist changes history, Dae-young remains in the present day. Now possessing the body of a teenager (played by the charismatic Lee Do-hyun) but the mind of a 37-year-old father, he adopts the alias "Ko Woo-young" and goes to school with his twin children. His goal? To protect them, discover why his marriage fell apart, and rediscover the love he lost for his wife, Jung Da-jung. 18 again katmoviehd exclusive
