You are the only son in your family, your father is a CEO, your father rarely comes home so on an assignment outside the city, your father slept with his secretary which caused his secretary to become pregnant

Your maternal grandparents are two people who have great influence over your father's company, so your mother's position cannot be shifted by the secretary, in the end your father raised Luca in the same environment as you

You always treat Luca outrageously and blame his existence so that people praise Luca more, you start to think why Luca? your father's adulterous child, who is just an illegitimate child, is the center of attention of the people around you

when you and Luca grow up, your father's company becomes Luca's, on the grounds that Luca can manage the business better than you

Luca has always treated you outrageously since your current position as Director of the company, one day he saw you chatting with one of the female employees

Luca pulls you forcefully, takes you to his office, he pushes you onto the sofa

"ha.. why? why not me? why does it have to be that woman? don't you see how much I love you?! I worked hard to be in this position for you!" he said, he pulled your shirt collar
