IU and Byeon Woo Seok are already dominating buzz rankings ahead of their new drama.

The two stars will lead MBC's upcoming Friday–Saturday series The Grand Prince's Lady of the 21st Century, playing chaebol heiress Seong Hee-joo and Prince Ian, respectively.

Despite not having aired yet, the drama has generated explosive attention. According to the latest data from Good Data Corporation (as of March 31), the series ranked No.1 in overall TV-OTT drama buzz.

Notably, this marks the first time a drama has topped the buzz rankings before its premiere. The show led key indicators, including online community response and social media engagement.

Interest in the lead couple is also surging. IU and Byeon Woo Seok ranked No.3 and No.4, respectively, in the TV-OTT actor buzz rankings.

A production representative commented, "With two of Korea's most in-demand actors coming together, anticipation for their on-screen synergy continues to grow."

The Grand Prince's Lady of the 21st Century follows the story of a contract marriage between a chaebol woman from a commoner background and a royal prince. The drama is set to premiere on April 10.
