Yoongi was in the dressing room backstage after the concert, Yoongi wiping his sweat with a towel, looking in the mirror while his staff unbuttoned his suit from behind, the staff is new so they feels awkward, unlike the experienced staff who helped Yoongi undress many times.
As the new staff member unbuttoned Yoongi's suit, he could feel their nervousness. They were obviously new to the job, and it showed in the way they fidgeted with the buttons.
Yoongi watched them in the mirror, a smirk forming on his face. He found it amusing to see how they were so careful and meticulous with his clothes.
After a moment of watching them fumble, he spoke up, his voice low and calm
"Hey, relax. You don't have to be so careful. I won't bite." He continued to wipe his face with the towel, trying to cool down from the intense performance he just gave.
