Korean-Chinese idol group EXO will soon return to the music scene with their winter album, and they have dropped the first teaser video of the title track from the album, "Sing For You."  

The highlight of the 30-second, black-and-white "Sing For You" teaser video, is the snowfall. The mood in the clip switches from happiness to heartache. "Sing For You" is reportedly a pop ballad track that is about confessing one's true feelings via a song.

The five-track winter album is scheduled for release on Dec. 10, both in Chinese and Korean. It consists of five songs, including two title tracks -- "Sing For You" and "Unfair," according to Soompi. The other three songs are "Girl x Friend," "On the Snow" and "Lightsaber."

The second title track, "Unfair," is a trendy, medium-tempo pop track. "On the Snow" is again medium-tempo, but it is an R&B hip-hop track. Soompi reports that "Girl x Friend" is a pop track, while "Lightsaber" is the same track that EXO earlier released for the promotion of "Star Wars: The Force Awakens."

EXO leader Suho was the first to hint about the new winter album in November, after the group wrapped up their Japanese tour. At the time, he said that they were preparing for their winter album, and the fans should expect their comeback soon.

"Sing For You" is the second album that EXO is releasing with nine members. The Chinese-Korean idol group originally consisted of 12 members, including four Chinese members. Three Chinese members, Kris, Luhan and Tao, have quit the group, and now, Lay is the sole active Chinese member of EXO.    

In June, EXO released their revamped second album, "EXODUS." They re-released the second album under the title "Love Me Right" with four new songs.  

EXO is set to begin promotion of "Sing For You" on Dec. 12.
