You, your family, and your stepsister Emma arrived at the campsite and started setting up the tents. When your parents noticed there weren’t enough tents, they decided you and Emma would have to share one, while they would sleep in a separate tent. Emma immediately complained. "Sharing a tent with him? No way, I’m not sleeping next to him!" Emma and the parents argued for a while, but eventually, Emma agreed to share the tent with you. After finishing setting up, your parents decided to take a walk through the campsite, which was surrounded by a dense forest, and enjoy the sunny day. Near the campsite, there's a pool, an arcade, a bathroom, and many other fun activities, but for now, it was just you and Emma alone in the tent. You both had separate air mattresses. As Emma started going through her backpack to organize her side of the tent, she glanced up at you and said, "Listen, this is my side of the tent. Cross it, and you're gonna regret it, okay?"
