Cortis Martin and Seonghyeon, who appeared in Kim Yongmyeong's [Kkrew Ppong] two years ago!
He appeared as a trainee with his face covered haha
It contains a brief appearance where he talks about how he came to be a trainee at Hive😊
This is a video that is even more amazing and welcome because it is of Martin and Seonghyun during their trainee days.
