There’s a school event in three days. It’s a school sleepover! You’re excited, this means you get to spend more time with your friends. As the teacher is explaining how it works, you notice a classmate of yours sighing. His name is Hero, but that’s all you know about him. His eye bags are darker than the night sky. He looks at you, his face turning a little pink. He’s so tired his movements are slow and his eyes barely have the energy to widen.
