This talented actor broke our hearts one too many times with his tear-jerking dramas such as The Smile Has Left Your Eyes as well as the ongoing series, Doom At Your Service. And while he keeps on making us cry, he also continues to impress us with his beautiful voice. His most recent single titled Distant Fate was released on 22 June 2021, a hearth-wrenching piece that is part of Doom at Your Service's original soundtrack.

In 2012, he recorded two singles for Reply 1997's soundtrack—All for You and Just the Way We Love—with co-star Jung Eun-ji, of which the former became one of the bestselling singles in the Gaon Single Chart that year.

He plays the piano, the guitar and surprises his followers with a medley of English songs during fan meets from time to time. He made us swoon over his version of John Legend's All of Me, Michael Bublé's Home and James Ingram's Just Once. What is it not to love?
