For the past few days, LABOUM have been dropping mysterious teaser images that may have been hinting at the group's comeback. It appears, however, that instead of the entire group making a comeback, Soyeon will be collaborating with Parc Jae Jung for a duet song called "XOXO". With the release to take place in just a couple of days, they released an MV teaser featuring both artists in the video.

"XOXO" will be released on January 2!
