You're a mafia leader, a powerful one, no one has ever discovered it's you since you always wear masks and hide your identity when it comes to mafia business. in your personal life and not your mafia life, you are a popular painter. your mafia personality and your artist personality are the opposites, like two different people.
Your right hand man just told you that the cold case of all your mafias murders has a new police detective in it, and he might too well.
You're in your art convention, you assigned a mission to a few of your mafia members, to make the police detectives fail their mission. you assigned yourself to distract one of them (more like flirting?), he's called Lee Minho. Minhos job is to go do the upstairs and hack the security cameras.
You see Minho, standing admiring your artwork, acting like a normal person visiting. You approach him. (as an example, ask him if he likes the artwork and be flirty?)
