## Early career and breakthrough
Sung Joon worked as a fashion model before moving into acting, debuting in 2011 with the KBS2 drama special *White Christmas*[3](https://www.koreatimes.co.kr/entertainment/shows-dramas/20200204/actor-sung-joon-reveals-he-is-married-with-child) • [4](https://sports.khan.co.kr/en/article/202608240842007). The same year he appeared in the SBS series *Lie to Me* as Hyun Sang-Hee[1](https://asianwiki.com/Sung_Joon).
His profile rose quickly in 2012. He played Kwon Ji-Hyuk, the leader and vocalist of a high-school band, in tvN's *Shut Up Flower Boy Band*, and took the lead as Jung-Hoon in JTBC's marriage-themed romance *Can We Get Married?*[1](https://asianwiki.com/Sung_Joon). In a 2012 interview he said that playing Ji-Hyuk gave him the confidence to continue his acting career[6](https://kaedejun.wordpress.com/2012/03/29/an-interview-with-sung-joon/).
## Television work
Through the mid-2010s Sung Joon built a run of romantic leads: Joo-Wan in tvN's *I Need Romance 3* (2014), Nam Ha-Jin in KBS2's *Discovery of Love* (2014), Choi Joon-Gi in SBS's *High Society* (2015), Yoon Tae-Joo in SBS's *[Hyde Jekyll, Me](https://www.edgepedia.org/hyde-jekyll-me)* (2015), and Choi Soo-Hyun in JTBC's *Madame Antoine: The Love Therapist* (2016)[1](https://asianwiki.com/Sung_Joon). His supporting role as Gon in the MBC fantasy drama *Gu Family Book* (2013) came between these leads[1](https://asianwiki.com/Sung_Joon).
For *Discovery of Love*, critics praised his portrayal of the insecurity and anxiety of a man in an unstable relationship, though early coverage questioned whether an actor in his early twenties could convey a thirty-year-old's emotional experience; he responded that he simply acted on what he genuinely understood and felt[7](https://www.allkpop.com/article/2014/10/sung-joon-talks-about-his-role-on-discovery-of-love-his-ambitions-as-an-actor).
His later career broadened across genres and platforms.

In 2025 he appeared as Park Chae-Joon in the first episode of TVING's *Chunhwa Love Story*, and he has roles lined up in MBC's *Perfect Crown* (2026) as King Yi Hwan, Netflix's *[Can This Love Be Translated?](https://www.edgepedia.org/can-this-love-be-translated)* (2026) as Na Jin-Suk, and Netflix's *Solo Leveling* (2027) as Woo Jin-Cheol[1](https://asianwiki.com/Sung_Joon).
## Film work

He then played Yoo-Jin in SHIN Su-won's *Pluto* (2013), a drama about academic anxiety and peer pressure at an elite school, and Dong-Wook in the "Cliff" segment of the anthology horror film *Horror Stories II* (2013)[1](https://asianwiki.com/Sung_Joon).

## Awards
Sung Joon won the Special Short Drama Actor award at the 2012 KBS Drama Awards, held December 31, 2012, for the KBS2 television movie *Drama Special: Wetlands Ecology Report*, in which he played Choi-Goon[1](https://asianwiki.com/Sung_Joon).

Sung Joon began South Korea's compulsory military service in December 2018. In February 2020, while still serving, he disclosed through a handwritten letter released by his then agency O& Entertainment that he had married a non-celebrity shortly before enlistment and that the couple had a child; he said he had switched to reserve status so he could stay with his wife during off-hours, and he was discharged in July 2020[3](https://www.koreatimes.co.kr/entertainment/shows-dramas/20200204/actor-sung-joon-reveals-he-is-married-with-child).
In August 2026 he signed an exclusive contract with Moan Entertainment, a newly established agency founded by Jeong Se-yeon, who had worked in artist management for 16 years; Sung Joon was the company's first signed actor[5](https://www.starnewskorea.com/en/star/2026/08/24/2026082408203386650) • [4](https://sports.khan.co.kr/en/article/202608240842007). He said the move was based on long-built trust with Jeong and that he intended to meet audiences more often through good works[5](https://www.starnewskorea.com/en/star/2026/08/24/2026082408203386650).
