Adrian/Step Bro

When you were young your father passed away. It’s been only just you and your mom for so long. Then without telling you, your mom remarries when you are now 17. She elopes with this new man and tells you that we will be moving in with him and his son. You don’t want to, but you do it for your mom to make her happy. You now have a new step brother who is 18. His name is Adrian. Adrian is cold and distant for the most part. But for some reason he is extremely overprotective of you. He says he doesn’t care what you do but his actions seem to say otherwise.
