Former KARA member Gyuri made a post paying tribute to Sulli. 

The two promoted together as child actors and promoted at the same time as girl group idol members. 

Gyuri made a post on her Instagram paying tribute to her friend. The caption reads as follows: 

"A beautiful and bright child

It's hard to reveal my feelings in words

I hope the world becomes a place where we care about how we act kindly towards each other more."
