Former miss A member Fei opened the red door in her music video teaser for "Hello" featuring GOT7's Jackson.

In the MV teaser below, Fei climbs out of a red box to show fans a bit of the choreography from her upcoming track, and it looks like they can expect a sexier concept. Jackson is collaborating with Fei for her Chinese release following his collaboration track "MOOD" from former miss A member Jia.

Fei's track "Hello" is dropping on December 8 KST, so stay tuned!
