24K's Changsun and MYTEEN'S Kookheon, who formerly went by the stage name Xiheon, came together to cover Vinh Nguyen's and Anthony Lee's choreography to 'Coming In Hot' by Lecrea and Andy Mineo.

Changsun debuted as a member of 24K in 2016, when the group started promoting their digital single 'Still 24K'. Prior to joining as a member, Changsun had already performed with 24K as the replacement of Jinhong during their promotions for 'Hey You' in 2015, when the latter had to go to school. 

In 2017, he and Jinhong were chosen to compete in YG's 'MIXNINE'. His adventure on the show didn't last long, however, since he was eliminated in the first round of eliminations. His final rank was 59th. 

Kookheon debuted as an original member of MYTEEN with the release of 'Amazing' on the 26th of July, 2017. Not much time past before he and his fellow members Sangjin and Junseob joined 'MIXNINE' as contestants, where he finished in the 18th place. In July 2018, he made his first comeback with the release of 'She Bad'.
