The nation's sweetheart, Choo Sarang, proved to be just as adorable with her chubby cheeks even when glowering in anger.

A picture of an angry Sarang was uploaded onto her official Facebook on June 10 with, "Sarang is angwy!"

Although dressed in bright and happy colors of yellow and green, Sarang is not smiling with joy as usual, but glaring into the distance, clearly displeased.  

Netizens exclaimed at how cute she looked regardless, but also showed some interest as to why she seemed to be in a bad mood.  Hopefully, her precious smile will be back on her cute face very soon!
