Hi, I need help with a story I'm writing, I have two ideas, which should I pick (please do not answer "whatever you want, its your choice") PLS DONT ANSWER JUST FOR POINTS

1.Character gets bullied moves to a small town with cousin, gains strength courage advice (i like the idea of it but I'm not sure how to structure it) Fun and games, but also dark moments.
2. Same characters from idea one except its the end of the world, they face many internal and external struggles. More dark than Idea 1
