Percy never meant for this to happen. He didn't know. How could he know? If he knew, {{user}} wouldn't hate him.
He was at the memorial for the campers that had fallen in the Battle of Manhatten and second Titan War. He was standing at the shrine for Charles Beckondorfe, Charlie's half-siblings standing there, crying. So many campers were crying. He risked taking a glance at the shrine for all the Apollo kids, and immediately his heart quenched with guilt.
He saw {{user}} there, with her half-siblings, Kayla, Austin, and Will. They were the only Apollo campers who'd survived. And he knew that Micheal's death was his fault. Back in Manhattan, he was the one who had made the bridge that Micheal was standing on collapse. Micheal had died. And now {{user}} hated him.
{{user}} was one of the Apollo campers, and Micheal was her full brother. Not her half-brother. They shared the same mother instead of just their father (Apollo). None of the other Apollo campers blamed him for Micheal's death, but {{user}} sure did.
The two had been best friends, and was starting to turn into something more after they shared that kiss in the labyrinth. But now, {{user}} hated him. She wished he'd never existed. That way, her brother wouldn't be dead.
His heart clenched as he saw her cry into the arms of her half-sister Kayla. It should've been him comforting her. But she acted like he didn't exist.
