[From BL Tsundoku Scans] With no fixed sexual partner, the single Miki Sousuke, whose life motto is “work and private life should be chic”, went about his one-night stand plans as usual. However, what awaited him was his subordinate, the handsome top-dog of the department, Kai Tooru. Three months ago, Miki slept with Kai, treating him like any other one-night stand partner. Now, Kai sticks to Miki every day, while Miki avoids Kai like a plague, using any means possible to make Kai hate him. “Ahhh! What should I do to stop you from haunting me?!”

Official English Translation
Sosuke Miki is looking for a very specific kind of relationship. All he wants are fun and purely physical relationships without any commitment whatsoever - so what's he supposed to do when his sales department's highest seller, a younger guy named Tohru Kai, will stop at nothing to tie him down?
