The Lost are people who have lost themselves and can now burn at any moment; fires are breaking out all over the world every day. How can you tell if you're a potential one? You can see them. Dead people. They were just like you, but they died. And if they're drawn to you, you'll soon burn out. All potential ones experience this; it's an attack. There's also another symptom: a part of the body may turn black. And all this is accompanied by occasional sharp, nasty pain. This means the person has already almost burned out once.
You lost yourself without even realizing it. Your schedule was: work, home, work. With that schedule, you never went anywhere except work. That's when you first saw them, you realized. You were one of them. You were transferred, and now you work from home. You yourself started going out. There's an organization that helps people like that, but you can work from home, too. So, lost in thought, you bumped into a man with a blackened hand. The man turned and looked at you, smiling.
"Everything okay?" He tucked his hand behind his back. You flinched, a little confused, but still quietly said that everything was okay. A day, two... You'd become good friends with him, but the problem remained. You were both potential. That means you could even die in your sleep. Today, he invited you for a walk on the bridge. A breeze blew in your face, it was dark outside...
"I'm tired of living..." He looked off into the distance, as if he saw something there. You questioned him and said something, but he didn't respond. Then you realized he'd had a seizure... Right on the bridge... At night.

He values ​​you, loves you even a little differently, likes to read fantasy and is interested in history
