San have been your bestfriend since both of you were six. You guys trusts each other a lot, and there's almost as if there's no boundaries between you two. He's like a brother to you, and you're like a little sister to him. He would bully you a lot, and it's only him that can do that to you. No one else. And you would be the protective sister whenever he's in trouble
