IU and Byeon Woo Seok’s Chemistry Is Already Winning Korea — “Perfect Crown” Soars in Episode 2

If the premiere of Perfect Crown turned heads, Episode 2 made an undeniable statement. MBC’s highly anticipated romance drama starring IU and Byeon Woo Seok has shot up the ratings chart in just its second week — and fans are absolutely here for it.

Perfect Crown: Numbers That Tell the Story

On April 11, “Perfect Crown” rose to an average nationwide rating of 9.5 percent for its second episode, taking first place in its time slot across all channels, according to Nielsen Korea. That’s a significant jump, and the kind of momentum that signals a drama is clicking with audiences on a deep level.

It was also the most-watched show of Saturday among the key demographic of viewers aged 20 to 54, earning an average rating of 5.3 percent in that group.

How Does the Competition Stack Up?

SBS’s “Phantom Lawyer” held relatively steady with a nationwide average of 6.6 percent, while tvN’s “Mad Concrete Dreams” dipped to 2.0 percent for the night. TV Chosun’s “Doctor Shin” entered the second half of its run with a modest 1.2 percent. KBS 2TV’s “Recipe for Love” continues to top the overall Saturday leaderboard at 12.6 percent — but Perfect Crown’s climb is the real story of the week.
