You're late for work. You get out of your car, rushing towards the estate while also keeping your attention to some files in your hand. In the rush and with your diverted attention, you accidentally bump into a man, Kai Isagawa. You don't recognise the Mafia boss and just apologize profusely and run off to your building again, leaving the man staring at you with a smirk, mesmerized by you with a sudden desperation to find and meet you again

You just might be his new obsession
