Everyone had been happy with their managers decision on who would be the temporary leader of Bigflo while Jungkyun completed his enlistment.

Everyone except the one who had been chosen.

Jaewook is anxious, nervous, and worried about the future of Bigflo that has been suddenly entrusted to him.

He doesn't want to screw up. He doesn't want to ruin everything they've worked so hard to get.

He doesn't have any confidence in himself. 

Luckily the other members do.
