UPDATE as of May 12, 2021:

Hendery went home to China due to personal reasons so he will not join the filming on the last week of May but Chloe will take some challenges on his behalf. The Ch.STRBM staff will make ways to make up with Hendery's absence.

Thank you for understanding

Also we have JunTo (Cherry Bomb's Tori & ACE's Jun) & WooYu (Cherry Bomb's Umi & NCT's Yuta)

BTW, Jeonah is the bridge for WooYu
