As reported previously, her fellow Cube family members Lai Kuan Lin, Jo Woo Chan, and Pentagon's E'Dawn and Wooseok make brief appearances in Jeon So Yeon's "Jelly" MV teaser, serving up gummy bears, ice cream, and more. The teaser also leaves fans wanting more with its repetitive catch phrase, "open the Jelly". 

The full song and MV will be out November 5 at 6PM KST.
