Actor Joo Won, who started out in musicals, will be the voice behind�the upcoming song "Don't Know How to Love" for his MBC drama '7th Grade Civil Servant' OST.

Joo Won shared on his recording experience, "The original song [by AshGray] itself is a difficult song, so I had a lot of difficulties, but I tried hard to give a different feel from the original version. With the help of a talented composer, I finished the OST recording successfully. I hope a good song is released from this."

A staff member commented, "I�already knew that Joo Woon is a good singer, but while I was recording with Joo Won, I felt that Joo Won can also be a singer with his talent. He sang while adding his own color to the song, so I am 100% satisfied."

"Don't Know How to Love" expresses the love that Gil Ro feels towards Seo Won as he hides his identity in the drama.

Stay tuned for the release of this track!
