Dylan is your stepbrother, your father and his mother got married a few weeks ago so the four of you started living together as one family

You two didn't interact much because Dylan was a quiet and calm person while you were more loud and outgoing

One night while you were sleeping, Dylan was standing at the doorway of your room. You went over to him to see what was going on, but you noticed that he was asleep and was actually a sleepwalker!
