As expected, little bits of chaos ensue at all corners of the globe, requiring someone to ground Mu-hee and bring her back to reality.
Such a job falls on her dutiful manager Kim Yong-woo, played by K-drama newbie Choi Woo Sung. Woo Sung's character proves to be a scene-stealer in the star-studded series, leading many to grow curious over him. To get to know him better, scroll through the facts listed below.
Who Is Choi Woo Sung?
Choi Woo Sung is a Gemini.
Woo Sung was born on May 21, 1997 in Goyang, a satellite city of Seoul located in the Gyeonggdi-do province.
Choi Woo Sung studied at Dongguk University.
With an early fascination with the performing arts, Woo Sung studied theater at Dongguk University. The school boasts of many notable alumni who are presently making major waves in the entertainment scene. Think the likes of Lee Seung Gi, Han Hyo Joo, YoonA, Kim Ji Won, Park Min Young, Jun Ji Hyun, and more.
Choi Woo Sung is signed with AM Entertainment.
Currently, Woo Sung is handled by AM Entertainment, a prestigious talent agency that handles Kim Woo Bin, Shin Min Ah, Ahn Bo Hyun, and many others.
In a past interview, Woo Sung expressed his appreciation for how supportive his seniors Woo Bin and Min Ah (who have been a couple for 10 years now!) have been to him. "They really take care of me. Min Ah even sent a coffee truck to Busan for my birthday. As far as I know, those are charged more depending on the distance," he recalled. "I want to take this opportunity to say thank you so much again."
Choi Woo Sung once gained 28 kg for a series role.
In 2024, Woo Sung was cast in retro crime series Chief Detective 1958. As Jongnam Police Station officer Jo Gyeong-hwan, the actor had to put on some weight to believably fulfill the role. More specifically, he had to gain about 28 kilograms in total!
In order to achieve Gyeong-hwan's ideal physique, he commited to bulking up and looking more like his character. "I thought I had done well to gain weight while doing martial arts. My body was like this, so it was worth it. If I hadn't increased my weight, it would have been difficult," he shared. During a physically intense scene, he was able to easily lift an adult man, which he attributes to his larger size. "I realized that they didn't ask me to lift him for no reason," recalls Woo Sung.
Choi Woo Sung won Best New Actor for his first lead role in a film.
Prior to Can This Love Be Translated?, Woo Sung starred in titles such as It's Okay to Not Be Okay (2020), My Roommate Is a Gumiho (2021), and I Am a Running Mate (2024).
His breakthrough, however, was in 2022, when he landed his first ever lead role as Ji-woong in the drama film Room Sharing. For effectively portraying a college student making ends meet, he won the Best New Actor trophy at the 42nd Golden Cinematography Awards.
