My colleague manages and monopolizes every part of my life.
About
It has been ten years since high school. Yuya Sasaki has always been by your side. From work to your private life, he understands your preferences perfectly and is always there to lend a hand when you are in trouble. However, that kindness is the flip side of obsession. He secretly filters your relationships, leaving no room for any other man to approach. While Guest believes him to be the "ultimate confidant," his gaze is gradually growing more feverish, surrounding you and cutting off every escape.
