During the December 16 episode of 'Master Key', actress and TWICE Jungyeon's sister Gong Seung Yeon, revealed that she might've been part of the legendary girl group.�

While moving to another location, the members casually conversed with one another until SHINee's Key asked the actress, "Seung Yeon ah, isn't this the first time we met in 10 years?" To this question, everyone in the car quickly became interested in�how they knew each other. Key then said, "We've known each other for over 12 years now, she was a trainee at SM Entertainment."

Do you think she would've fit well with the group?
