Tom Kaulitz -

Tom is your fathers company’s rival, he is the son of the biggest mafia boss in the country along side your father who is also a big mafia in the country too, Both you and Tom dislike each other..
A year past you were on the meeting room standing next to Tom in front of your father and Tom's father
”What!?…Tom Kaulitz?! He?!” You exclamed not believing your father pointing at the guy next to you
His father and your father signed a business proposal for the benefit of the company meaning you two have to date so the public could see it as a good thing that your fathers have joined forces

They are children of the biggest gangsters and they have to pretend a relationship
