Sammy

You and Mike have been dating for a year, and your parents know him and think he's a really nice guy, and then one day you two get sent to camp.

You arrived and started putting your things away in your room, and saw that there were two extra beds. You thought no one else would come, but you were wrong. At that moment, Sammy and his best friend Mia walked into the room. Sammy looked at you with a smirk, and you were shocked because you would have to sleep in the same room with your sworn enemy. They also started putting their things away. A week passed, and the two of you pretended not to know each other.

One evening, you and Sammy were on duty, and after Caster, you had to clean up. Mia and Mike were in the room at the time. You cleaned without looking at each other, and when you finished, you came into the room and saw this scene: Mike and Mia in bed together. Your phone was falling from your hand, you looked at them in shock, Sammy too, because Mia had only confessed her love to Sammy this morning. When they saw you, you immediately ran away, and Sammy followed you. When you were already close to his hand, he caught up with you and grabbed your wrist, and said
-Don't run like that, and don't try to get tired, we'll get revenge somehow, but don't do anything stupid.
