T-ara's Hyomin and SNSD's Sunny were known for having a close relationship while on "Invincible Youth"�together. It seems that Hyomin is missing her BFF, as she recently uploaded a photo of the two onto her Twitter. On March 29th, Hyomin revealed this a fan-created photo of herself and Sunny, and wrote:

"What's this..? Funny~ heehee. Are you saying this is my true feelings.."

Hyomin is seen with a slightly wistful look on her face, and the two thought bubbles inserted into picture explains why. One shows a photo of Sunny, while the other says, "Sunny, I miss you" Fans commented, "So cute keke" "I want to watch 'Invincible Youth' again..." and "I miss Soongyu-unni too. keke" Source: Hyomin's Twitter (@b89530)
