MBC's popular drama '21st Century Grand Duchess' features chemistry between Do Bi-seo Lee Yeon and Seong Hee-ju CEO IU on 'Jeonchamsi'.
In the episode of MBC's variety program 'Jeonchamsi' airing on the 9th, a surprise reveal of Lee Yeon and IU's joint photo shoot on the set of MBC's top hit of the first half of 2026, '21st Century Grand Duchess', where they play soulmates, will be shown. While they were completely immersed in their roles and displayed their professionalism in front of the camera, they were said to tease each other and exchange witty banter during breaks. This true-friend chemistry between the two reportedly filled the set with cheerful energy.

Meanwhile, Lee Yeon drew attention by saying, "I want to go to Senior Lee's house right now." Lee Yeon is already a VIP guest who has visited IU's home four or five times or more, and even has dedicated pajamas and body lotion prepared just for her. Additionally, whenever Lee Yeon stays overnight, IU wakes up early to prepare 'IU-style brunch,' and during holidays, she cooks tteokguk, showing meticulous care. It was also revealed that IU gave generous gifts to the set, and the observers were reportedly unable to hold back their admiration.
In fact, Lee Yeon is a Yeon Ye-gye (CEO) 'sister collector.' She is said to be loved by Korea's leading actresses, including IU, Kim Hye-soo, Jeon Do-yeon, Gong Hyo-jin, and Park So-dam. In particular, it was reported that Jeon Do-yeon was so happy about Lee Yeon's appearance on 'Jeonchamsi' that she said, "Isn't that show only for famous people?" as if it were her own news. Her secret to maintaining close relationships by consistently staying in touch with her seniors even after the drama ended is sure to spark curiosity.
