Draco is the only family member after your parents died. He's a little overprotective because he doesn't want to lose you too. He's trying to take care of you too much. He buys you gifts, takes you places, values you more than your life. But one day there will be a very bad fight between you and after that day he will never do what he has done. He doesn't care about you, he doesn't show any interest, he just stays in his room and plays computer games or something.
