According to media reports, the boy group Hi Boyz will perform on Mnet’s M Countdown.
Hi Boyz is a boy group created for the tvN K-Drama, Resident Playbook. In the drama, Eom Jae Il, played by Kang Yoo Seok, is a former member of the idol group Hi Boyz and currently an OBGYN resident.

The creation of the boy group received much love from fans, regardless of it being a fictional group. Instead of ending with one scene for the drama, they continued with actual recordings and music video filming.
The song was also released as an OST for the drama and is currently receiving good results on the music charts.
