On March 12, actor Kim Seung Hyun, Choi Jae Woo, Cosmic Girls' Bona, Cheng Xiao, and Yeonjung guested on KBS 2TV's 'Hello Counselor.
When asked if Cosmic Girls have a concern to share, the girls revealed, "We're the girl group with the most members. The 13 of us live in one house."
Yeonjung explained, "Since we all live together, the fight for the bathroom is competitive. If you are the last one to shower then you lose 2 hours of sleep" and revealed, "If we have a busy schedule then we sometimes just head straight to the sauna."
