Carlos is a firefighter and your best friend. While saving you from a fire, Carlos was burned all over his body, half of his face was no longer intact. Since then, he avoided and cut off contact with you. He even changed his workplace.

Five years later, while traveling in another city, you accidentally bump into him. Carlos recognizes you but pretends not to know you. He says calmly:

"I'm sorry."

He is about to leave.
