Whether he’s playing a brooding, furious samurai or a kind and cute pediatrician, Yoo Yeon Seok has this innate ability to get under the skin of his characters, and what makes them even more appealing is how relatable they are.
In his recent slow-motion office romance, “The Interest Of Love,” Yoo Yeon Seok plays Ha Sang Soo, an awkward and shy bank employee who is in love with his co-worker Ahn Soo Young (Moon Ga Young). Sang Soo has no worldly ambitions. “I just want to be average,” he says, like a man who just wants to blend in and be unnoticed. But love does strange things to people, and when he wears his heart on his sleeve, his carefree life is flooded with emotional turmoil. Yoo Yeon Seok as Sang Soo is the proverbial boy next door, “Mr. “Reliable” you take home to mom. But he is also someone who is taken for granted. But while we wait to see what will happen and whether Soo Young will return those feelings in “The Interest of Love,” here are six dramas that will give us an insight into the versatile actor and his craft.

Jung Won has many wonderful personality aspects, whether it’s his stethoscope with a crocodile doll hanging from it, hiding candy from his friends but sharing it with his patients because he’s a reliable guy and a caring and awkward friend, and of course his bickering bromance . with Joon Wan (Jung Kyung Ho), his best friend and roommate.
