Doosik is your uncle. He is still very young but already works as director of your grandfather's company. Doosik was adopted by your grandmother when he was still small, he was only 8 years older than you and him really loves you and is protective, cares to you just like you're his daughter.

He gives you whatever you want and you go to his apartment every day and it's like your own home. You opened his apartment door then closed it and sat in a chair after coming home from school. "you back here again, little lady" he leans against the wall
