JTBC weekend drama "Waiting for Kyungdo" unfolds around the complicated relationship between Lee Kyungdo (played by Park Seojoon) and Seo Jiwoo (played by Won Ji-an). The drama deals with the story of the two who reunite through an affair scandal, drawing increasing attention to their connection.

Lee Kyungdo and Seo Jiwoo first met on a university campus. Seo Jiwoo happened to see Lee Kyungdo while visiting the campus to meet a friend and became interested in him. Later, Seo Jiwoo began to get closer to Lee Kyungdo through a club recruitment festival. Seeing Seo Jiwoo sitting at the theater club booth, Lee Kyungdo fell for her at first sight. Lee Kyungdo became a reliable support for Seo Jiwoo, but at that time, he did not know that she was the daughter of Jarim Apparel. Curiosity is growing about how Seo Jiwoo's lie—that she approached Lee Kyungdo as a person, not as the daughter of Jarim Apparel—affected their relationship.

Lee Kyungdo and Seo Jiwoo went through their fresh first love but broke up for certain reasons. However, they reunite due to an affair scandal. Thanks to the scandal, Seo Jiwoo successfully divorces her husband and comes to see Lee Kyungdo in person to express her gratitude. Lee Kyungdo still keeps the T-shirt filled with memories of Seo Jiwoo, and Seo Jiwoo's heart is shaken by Lee Kyungdo's worried words. Their relationship is lukewarm like an old T-shirt but still retains warmth.

When Seo Jiwoo tries to leave for the UK to avoid further commotion, Lee Kyungdo stops her. Seo Jiwoo thinks her presence will cause another disruption in Lee Kyungdo's life and tries to leave Korea for his sake. However, Seo Jiwoo's older sister Seo Jiyeon (played by Lee El) asks Lee Kyungdo to protect her sister on her behalf, as she is suffering from Alzheimer's. This leads to a new turning point in Lee Kyungdo and Seo Jiwoo's relationship. Whether it is lingering attachment, love, friendship, or humanity, Lee Kyungdo blocks Seo Jiwoo's departure with emotions he cannot clearly define.

This drama captivates viewers through the complex emotional lines between Lee Kyungdo and Seo Jiwoo. Interest is gathering on how Lee Kyungdo's sincerity and Seo Jiwoo's reactions will unfold. All these stories continue in episode 3 of JTBC weekend drama "Waiting for Kyungdo," airing on the 13th (Saturday) at 10:40 PM.
