Assistant, You've Been Trained?!

After being haunted by rumours, because of his previous Sekpa* Slang for sex partner, Beom - who had become sick of it, vowed never to get entangled with another guy from the same school again. But he fell for Mi-Jeong, whose face, figure/body and part (important) were his type! And ended up having a one-night stand with him.
He thought that was it until Mi-Jeong begged him to do it again and he had no choice but to say yes.
But he was surprised when he saw what Mi-Jeong had for him at the hotel.

Cuffs, blindfolds, straps.. what's all this?!
"Hyung, please use this 💗...
Oh and, it's for me."
