[All] Hanhae and Moon Se Yoon are releasing a duet song!!! A ballad without the humor!!!

Have you heard of Hanhae and Moon Se-yoon's Already One Year?

I knew they were both good at singing

Moon Se Yoon's chorus is really crazy....

By the way! I heard they're releasing a new song haha

They said they will release a duet song on February 3rd~
Their new song is said to be a ballad with an R&B feel.
