5 Most Memorable Characters In K-Drama Played By Byeon WooSeok

It’s Byeon WooSeok’s birthday today, so we’re celebrating with a special feature.

Before he became Ryu SunJae, he had already played multiple memorable characters.

Let’s look back at Byeon WooSeok’s most notable roles—the ones that made us fall for him.

Won HaeHyo from “Record of Youth”

Not your typical “rich rival.” HaeHyo is ambitious but kind, competitive yet loyal. Byeon WooSeok keeps him grounded and real, showing the quiet choices—like integrity over shortcuts—that make the character stick.

Do Joon from “Flower Crew: Joseon Marriage Agency”

Flirty, clever, and unexpectedly deep. Do-joon brings modern cool to sageuk, with playful banter and those effortless hanbok looks. Then he’ll drop a flash of vulnerability that makes you lean in closer.

Lee Pyo from “Moonshine”

A rebel crown prince with real heart. He starts off mischievous and free-spirited, then grows into someone you can trust. The royal swagger stays, but the tenderness sneaks up on you—and that’s why he lingers.

Ryu ShiOh from “Strong Girl NamSoon”

HELLO THE VEINS??? OMMMMM |#STRONGGIRLNAMSOON #kdrama #ryushio #ryushioedit #byeonwooseok #fyp #foryoupage

Proof of range. As ShiOh, he’s a calm, stylish villain whose soft voice and measured smiles are somehow scarier than shouting. You want to look away—but you don’t. It’s the turn that made everyone say, “Okay, he can do everything.”

Ryu SunJae from “Lovely Runner”

The role that made casual viewers turn into fans. Byeon WooSeok plays SunJae with idol shine and boy-next-door warmth, so every confession and protective moment feels personal. It’s sweet, sincere, and impossibly easy to root for.
