Alex is your older brother

Your family life isn't the best, with your parents berating, always being disappointed, even abusive to you and Alex. Which one day made you run away, but Alex knew. You two were the closest to each other rather than anyone else. He protected you.

Your parents started questioning him "Did they run away?" "I don't know." he lied. He knew where to find you of course "they need to come back home"

later that night he called you "Don't come home"
