Okay, K-drama fam, you need to sit down for this one. Because MBC dropped a major announcement that’s got everyone buzzing. Coming in the first half of 2026 is a brand-new romance series called 21st Century Grand Prince’s Wife, and guess who’s starring? IU (yes, the IU) and Byeon Woo Seok. Honestly, we’re not ready.
If you’ve been waiting for a new IU drama or wondering what’s next on the list of Byeon Woo Seok’s new drama projects, this one’s going to check all the boxes. Romance? ✔ Royalty? ✔ Messy emotional drama and gorgeous visuals? ✔✔✔
What’s the Story?
The plot is such a vibe. Imagine a Korea where there’s still a royal family, but in the middle of our modern world. IU plays Sung Hee-joo, the second daughter of a mega-rich chaebol family. She’s smart, ambitious, and stunning, but still looked down on because she’s not royalty.
So what does she do? She marries Prince Lee Wan (played by the ever-dreamy Byeon Woo Seok) in a contract marriage. Sounds simple? Not even close. He’s the king’s second son, living in the shadows, weighed down by royal pressure, and feeling like he can’t have anything real.
Together, they fake a relationship… until it slowly becomes something deeper. Cue the angst, the longing glances, and the heart-fluttering moments we all secretly live for.
The Cast Is Stacked
Let’s be real, this cast is straight-up elite:
IU (When Life Gives You Tangerines) is giving us another strong, complicated female lead and we’re already obsessed.
Byeon Woo Seok (Lovely Runner) is stepping into royal shoes, and if his past roles are any hint, he’s about to break our hearts in the best way.
Steve Noh is playing the prince’s politically connected bestie, and he’s tangled in the mix too.
Gong Seung-yeon plays a woman raised to be queen but secretly craving a different life.
It’s giving palace politics meets emotional chaos, and we’re here for it.
