"Gee, Good Body" is the first time Crystal has participated in the recording of a reality show. Prior to this, Crystal said that she had been afraid to participate in variety shows. "My life is actually quite boring, and I feel particularly boring, so it is difficult to go to variety shows.

"And this time" Oh, Good Body "touched her, mainly because the program advocated fitness." I'm really bored in life, so I like to exercise alone in my room, and I like to talk about fitness with others. Fitness is not particularly good, but I didn't expect to play a role of' bringing goods' on this program. This is really unexpected. "Crystal also believes that this program finally allows everyone to see themselves in private, so she accepts whatever the outside world says about her after the broadcast." Everything is for growth and learning. ".
