Rainbow's Yoonhye recently showed support for her cousin Roy Kim.

On the 19th, Yoonhye wrote, "I'm planning to go cheer on my cousin with my family today and eat together for the first time in a while. I'm going to tell him fighting! Everyone, text vote Roy Kim, okay?" She also tweeted, "#0199 Roy Kim vote go go!" with photos of her holding a support sign for Roy.

Yoonhye and Roy were previously revealed to be cousins when he auditioned for 'Superstar K4'. In August, she first tweeted, "My cousin is going to be on Superstar K4. Roy Kim. I haven't seen him in a while because he went overseas to study, and I'm seeing him on TV. Sangwoo grew so big. Fighting!"

Since then, she has continued to showcase the family bond between herself and the handsome contestant, as she helped promote him in various ways.
