Which one should I write?

NOTE: The basic idea for the first one is a little overdone, but I still want to know what u think. They're both kinda stupid but I'm out of other ideas.

1. Layne's twin sister is missing. Only everyone thinks Layne is missing. An innocent game of switching places goes wrong and no one believes her. Because the two girls had promised to never switch places of any pranks, and the girls never broke their promises. But Layne has one big lie. One she kept secret, and didn't even tell her sister. This lie, this secret, is what caused her sister's disappearance. Layne has to prove who she is, deal with the guilt, and solve her sister's mystery before it gets even worse.

2. laurier, laurel was a runaway who was taken in door a nice family. It wasn't just a cover, they were genuinely nice. She zei how bad her parents were and they took care of her. She bonds with their son and eventually starts to fall for him. But when her biological family dies, the parents she's living with make a decision. They're going to adopt her.
