Channel A's new Monday-Tuesday drama "Queen of Masks" (directed by Kang Ho-jung, written by Lim Do-wan, produced by The Great Show, Ramong L'rain, planned by Channel A) is a story about the war of jealousy and desire among four friends who face a whirlwind in their lives due to one man, as the truth hidden behind masks is revealed when a former friend who became a murderer because of their lies ten years ago appears in front of three successful friends.

Yoo Sun takes on the role of Yoon Hae-mi, the "Queen of Jealousy" and the first Mariella Hotel vice president who comes from an ordinary employee background. As a talented vice president on the verge of being promoted to president, Yoon Hae-mi faces her biggest challenge when her friend and enemy from ten years ago, Go Yu-na (played by Oh Yoon-ah), reappears.

The stills released today (20th) capture Yoo Sun's confident transformation into Mariella Hotel vice president Yoon Hae-mi. Her intense presence, seemingly unfazed by the attention of others, draws attention as she fiercely climbed her way up to the vice president position.

Yoon Hae-mi, an owner of unyielding determination who won't be satisfied until she gets what she wants, overwhelms the atmosphere with her resolute __EXPRESSION__ and sharp gaze.

Her contrasting looks, from a relaxed smile to suddenly wiping away any trace of laughter, create a tense atmosphere for the viewers.

Yoon Hae-mi, captured in the dressing room, reveals her provocative charm in a glamorous leopard-patterned see-through look. Although she appears confident, her serious __EXPRESSION__ suggests that she is deep in thought about an unusual event.

It raises curiosity whether she will overcome the imminent crisis and secure the position of president after pouring all her luck and competitiveness into her life.

The production team of "Queen of Masks" said, "Yoo Sun amazed us with her perfect immersion into the character of Yoon Hae-mi from the first shoot, as well as her meticulous character research. Please look forward to how she portrays the colorful life of Yoon Hae-mi." The drama, a collaboration between director Kang Ho-jung and writer Lim Do-wan, will air for the first time on Channel A in April.
