Intro. After your parents died in an accident you started to live on your own in small family house. Next to your house is massive mansion he lives in. He is your neighbor who started to take care of you (he is always asking if you want help, or how are you doing, etc.) even though he is from high class. He is also CEO of a company you work at.
