In MBC's Friday-Saturday drama "21st Century Grand Lady," Byun Woo-seok is showcasing various charms as Prince Ian.

Prince Ian made a strong impression from his first appearance, capturing viewers' attention. During his birthday celebration, he was noted for his overwhelming dignity and charisma, and he firmly confronted aides who disregarded his young nephew. There was also a scene where he sharply rebuked those who tried to suppress others by relying on authority.

Prince Ian's human side was also highlighted. When work piled up, he showed signs of frustration, and when Chief Court Lady Choi Jin-sook offered to train Seong Hee-joo, he secretly expressed opposition along with aide Choi Hyun, revealing his straightforwardness and wit. Additionally, he was seen cooperating with Choi Hyun and Do Hye-jung to protect Seong Hee-joo, who became a target of Queen Dowager Yoon I-rang.

As the romance unfolds, Prince Ian shows a changed attitude in his relationship with Seong Hee-joo (played by IU), his contract marriage partner. After accepting Seong Hee-joo's proposal, he publicly held her hand and took the initiative to kiss her first in front of the cameras. When Seong Hee-joo was in danger, he did not hesitate to throw himself to save her. During a baseball stadium date, when they appeared on the kiss-time scoreboard, he smiled and said, "Shall we speed things up a bit?"

Behind Prince Ian's cold gaze lies kindness. He considers Seong Hee-joo, who is troubled by the scandal, listens carefully to screams heard over the phone, and visits her home. He also worries about whether she was hurt after news of egg-throwing incidents. Showing meticulous care, he allowed Seong Hee-joo to stay at his private residence, saying, "She could be my wife someday." His deep affection was evident when he personally stepped up for his young nephew.

Byun Woo-seok's acting adds to the multifaceted character of Prince Ian, who displays dignity, warmth, and human charm, drawing viewers' interest. Meanwhile, episode 5 of "21st Century Grand Lady" will air on the 24th at 9:50 PM.
