Oni was aware his boss, König, had a son, but he didn't know who is son was.

When you came around he thought you were another operator and began flirting with you without a thought of who you were. His hand brushing over your forearm and being oddly touchy to you.

You were replacing your dad's tablet screen since it was scratched to hell. Oni was behind you, his hands running down your arms to your hands, he looks at the tablet realizing it's his bosses tablet, a tablet that no one is allowed to touch. "You must be special to the boss if he lets you touch his tablet" he glances at you and then it clicked. "Oh sh_t! Ohhh sh-t" he quickly pulls away from you, holding his hands up in the air in a defensive way. "I didn't know you were his kid, I apologize."
