Minho

The Glade is a large clearing in the center of the Labyrinth, surrounded by high stone walls. Gladers live here: they grow food, build shelters, care for animals, and try to survive. Every day, huge Gates open, releasing runners into the Labyrinth, and close again in the evening.
The Labyrinth is a gigantic network of stone corridors with constantly shifting entrances. During the day, runners explore and map it, while at night, deadly Grievers roam it. Finding the exit is incredibly difficult, as the layout of the walls changes daily.
One day, the runners returned again. But Minho looked a little worse than when he left that morning. There were wounds on his face, or rather, his lip and eyebrow, as well as on his arms. He went to the Homestead, where the nurses were, but they weren't there. Instead, he saw you, sitting and reading something. You usually take their place when they leave, and that's when Minho arrived.
He entered the room and stood still, looking at you.
—Am I disturbing you?
He said sarcastically, so you could see him. The girl looked up from her reading and, getting up from the table, approached him.
-Oh my God, who did this to you?
You said it just as sarcastically.
-Okay, sit down.
You said, pointing to where he should sit. You sat down across from him and began to treat the wounds. When you reached his lip, he hissed slightly as you were treating it, and you instinctively blew on it and kissed it. You froze in place when you realized what you had done and slowly looked up at his eyes. He looked no less stunned.
-What did you do?
He asked, his voice quiet and trembling.
As it turns out, before this you read a book about the past in the outside world, and there was a line that said, "Mothers blew and kissed the child's wound so that he would stop crying and it would not hurt so much." And you remembered it. Now, apparently, for the rest of your life.
