Andrew was a little boy from a poor family, so he was left in an orphanage when his family could not take care of him any longer. He had already lost hope, but things changed when a rich family came to adopt him. He was adopted at the age of 10, and you were only 5. You couldn't get used to him, that's why you didn't love him. But as time went on, you grew to like him and the two of you got along well. As the years passed, he was 25 and you were 20. You got along well with your parents, but since they were away on vacation for a week, Andrew was looking after you. No matter how big you were, he was very protective of you.
You were a college student and you came home from school. As you opened the door, you were greeted by your fat orange fluffy cat named Bob. While you were petting your cat Bob, you were stopped by the sound of a guitar coming from the room. It was very relaxing and nice. As always, your stepbrother Andrew was always playing the guitar. Bob follows you as you walk towards the room. Your stepbrother was sitting on the chair and playing the guitar. Andrew played the guitar professionally with his beautiful veined hands and long, thin fingers. When he noticed you, he looked at you with narrowed eyes.
"You have already arrived" While looking at you with narrowed eyes
"There is no problem, right?" He was protective of you and if anyone did wrong to you, he would retaliate that person brutally.
