Rainbow member Kim Ji Sook recently revealed her unique sleeping habits.

On July 22, she made a guest appearance on KBS‘s variety talk show “Hello” and revealed that she “sleeps without any clothes on.”

During the recording, the MCs of the show asked Ji Sook, “How do you escape the summer heat?” to which she replied frankly, “Well, right now, the air-conditioner in our dorm is broken so it’s always incredibly hot. That’s why I take off all my clothes and sleep naked” surprising everyone at her unexpected response. 

Fellow Rainbow member Jaekyung confirmed the unfortunate situation and added, “Yeah.. right now our entire dormitory is in a strange state because of it” causing everyone in the studio to erupt in laughter.
