Yoo Soo-bin and Lee Yeon Become IU and Byun Woo-seok's Assistants... Anticipating Their Roles in 'Perfect Crown'

Actors Yoo Soo-bin and Lee Yeon will showcase a fantastic chemistry as an assistant duo comparable to the great royal couple.

In the new MBC Friday-Saturday drama set to premiere in April 2026, Yoo Soo-bin and Lee Yeon will play the closest aides to Seong Hee-joo (IU) and Lee An-dae-gun (Byun Woo-seok), injecting vitality into the drama.

First, Yoo Soo-bin takes on the role of Lee An-dae-gun's assistant, 'Choi Hyun'. Despite his pure appearance, Choi Hyun possesses a fiery loyalty, serving Lee An-dae-gun, who took him in as a child, as if his life depended on it. Sometimes, he expresses affectionate nagging, forming a 'bromance' that transcends the master-servant relationship, raising viewers' expectations.

On the other hand, Lee Yeon transforms into 'Do Hye-jung', the chief secretary of Seong Hee-joo, the representative of Castle Beauty. A cool character from overseas, Do Hye-jung takes her status lightly, as if it were just a blood type. Although she may not fully understand her boss Seong Hee-joo's position, who faces class limitations, she genuinely supports her ambitions and is expected to showcase a strong 'woman's romance' as a 'soul partner'.

The stark contrast in styles between the two in the released stills also catches the eye. Yoo Soo-bin maintains a neat suit that exudes the dignity of an assistant, while Lee Yeon flaunts a sophisticated and fashionable styling appropriate for a beauty industry secretary. Especially with the contract marriage between Seong Hee-joo and Lee An-dae-gun, the time the two assistants spend together is expected to increase, making their unique 'assistant' banter another point of interest.

〈Perfect Crown〉 is set against the backdrop of a constitutional monarchy in the 21st century in South Korea, depicting the fate of a commoner heiress and a king's son who can possess nothing. This work, which will bring a new narrative of breaking class barriers to the Korean drama market, will be coming to viewers as an MBC Friday-Saturday drama this April.
