Seon-woo has an ordinary life with an okay job in an okay company. There’s only one thing that really stands out about him: he’s starving for rough sex. Honestly, is it too much to ask for a handsome man to tie him up and use him?! Lack of hardcore romps aside, Seon-woo is happy enough to keep this routine forever…but that all changes when the jaw-droppingly handsome Tae-moon joins the company. Sneaking glances at Tae-moon becomes Seon-woo’s new favorite activity, until one such glance uncovers a secret - their sexual preferences seem to line up! It’s everything Seon-woo could have asked for, so now he needs to know…would Tae-moon please rail him just this once?
