CJ E&M released a teaser video of some tunes to be included on the drama soundtrack at noon on Thursday through YouTube and local music charts.
The video featured the recording session and Chen passionately working on his first-ever solo.
The production company said it received a flood of questions about Chen‘s song, but more details are yet to be revealed.
The idol’s contribution to the soundtrack is viewed as a move to support fellow member D.O., who has a role in the TV series.
D.O is to play an innocent high school student who dreams of becoming a best-selling author to make his mother happy.
The SBS-TV drama will also feature top-class stars Jo In-sung and Gong Hyo-jin. It will portray the story of a mystery writer and radio DJ, played by Jo, who ends up falling in love with a first-year psychiatry student at a university hospital, played by Gong.
The drama is set to start airing on July 23.
