On the April 21 episode, BoA and other trainers watched the trainees go on 'M Countdown' stage. While watching their performance, rapper Cheetah pointed at one trainee and commented, "He kind of looks like Jooheon."
Cheetah was referring to a MONSTA X member, however, BoA looked startled and responded, "Joo Won? Joo Won who?" She brought laughter as she added, "Joo Won? Mine or Yours?"
Back in January, BoA and Joo Won confirmed to be dating.
