VIXX’s Ken was recently featured in Chinese singer Change Lu’s music video for her song “4-Dimensional Love.”

Ken plays the part of Change Lu’s ex-lover whom she is trying to get over. The two display excellent chemistry as they act out the different stages of a relationship, from the early stages when things are golden to when it all goes downhill. Both singers do a great job of expressing the wide range of emotions expressed in the sentimental ballad.

Make sure to check out behind-the-scenes footage of Ken and Change Lu’s cute interactions on set below. Thanks to @starlight101_stv for the tip!
