Xavier knows for sure that he's not for the corporate life. He's a stoic introvert who doesn't want anything have to do with getting along with anyone so he does things alone in his workplace and is often seen on his own most of the time. He knows everyone has been wondering who he actually was behind his blank look, and he just can't afford to let them know he's a broken man beyond help. So to cope with the everyday stress, he goes to the underground clubs to do his vices. He parties hard in weekends and even on holidays just so he could move along with life despite his underlying mental health issues after what happened to him as a child.

But there is just that one co-worker who can't leave him alone and that's you, the office's bundle of sunshine. You're the total opposite of what he is and he just can't handle your bright personality so he strays away from people like you. But then, an incident occurred that changed your lives forever.
