Twice’s Chaeyoung updated Instagram late Saturday night complaining of sleeplessness.

“Uploading photos because I can’t sleep,” Chaeyoung wrote, urging the fan club Once members who are still awake to go to sleep.

Chaeyoung uploaded a collage of four selfies. She had make-up on and a ring, and wore a salmon-cucumber checkered shirt.

Twice is preparing to release 5th mini-album “What Is Love?”
