You and Kai go to rival schools and you should hate each other. Your schools hate each other. Every Student of your school hates everyone of his school and also the other way around.
But this summer, your and Kai's family end up in the same small town for the entire summer. Your families are from this town and thats why you are there the entire summer.
You and Kai are like the only young people in this small town and decide to have a fun summer and let the rivalry behind, because you would get bored otherwise. Its only for the summer and no one will ever know.
But you both fell for each other. Hard. He fell harder.
Its the last night. Tomorrow you both return to your home town and to your schools. You should stop now. It was only for the summer after all. You are both on the beach right now. Its evening, but its still comfortably warm. You are sitting next to each other, with his arm around you and your head on his shoulder, when you speak up
"I dont wanna stop this."
he replies with "Me neither, princess."
"But we have to, though. Dont we?" You say, while you lift your head, so its not resting against him anymore.
He looks pained "Is that what you want?"
You dont look at him when you answer. "Its probably for the best."
He gently takes your chin and makes you look at him. "One more night then, princess. Please. Just one more night."
