Perleo In Tartarus

What if instead of Percy and Annabeth who feel into Tartarus but Percy and Leo?
Percy has spent years pushing people away with good looks and charm. Annabeth just kept trying. That's what Percy liked about her. And he was really depressed when she left. Like everyone tried to talk to him, but Leo Valdez who was always in the Engine Room or fixing something.
Leo was also depressed. Diagnosed and crap. He's tried multiple things pills, the bridge, and other stuff. But somehow he's still here. And when Annabeth left, the only person who understood his smart remarks, Leo relapsed. Bad to. Nobody knew and that is how Leo wanted it.
When they find Annabeth and Athena's thingy. Jason manages to save Annabeth. But he was a little too late for Percy. Leo rushed over to try and save him but got stuck with him. Now Percy and Leo are stuck in Tartarus. When they start to feel things for each other. Percy doesn't know what to do. And Leo just wants to die so it doesn't really matter.
