It's a sterek story

Derek takes the pack on a vacation weekend to a beach, where they share a house. Derek and Stiles are forced to share a room after Allison and Scott claim one room, and Lydia claims another for her and Jackson. This leads the two towards bonding and more.

The Wall was built around the city to keep the werewolves out, but Stiles and Scott decide to sneak outside of it. It may be completely traumatizing since they run into one of the werewolves, but they manage to get out of there alive. Scott vowed to never go out again, but Stiles... Well, he keeps going back. Those steel blue eyes shine like stars, after all.
