The '2017 JOY OLPARK FESTIVAL' was held in Seoul Olympic Park and a fan cam capturing the funny moment is going viral.
In the footage, Heize was in the middle of singing "Don't Come Back", setting the atmosphere when suddenly the audience began to laugh, causing the singer to turn around and look at the big screen behind her.
The giant screen featured a hardcore uncle fan wearing a bright neon-colored tank top as he danced to Heize's song, making a heart gesture with his arms in addition to other funky expressions.

Seeing this, Heize couldn't help but laugh out loud at the surprising sight, which caught her off-guard, as she tried to cover her face in embarrassment.
Maybe the song title should've been "Don't Look Back" instead. Check out the hilarious clip above!
