Edit: Maria explains what’s going on in the comments.
oh sorry I meant duet of Naeng Myun with Park Myung Soo. (: The reason I said solo was because in this preview..Jess completely takes the reins with the song and Myung Soo is just speechless lolol.
Refer back to this post on more news about the song!
