Who is the Red Lady?

Sonia drowned in a deep river. He could not swim because he had run out of energy to reach the surface and was too deep. However, someone swam into the river and brought it to the surface. Sonia woke up and had reached a cave.

"Where am I ?"

"My door." Said the young man, "You better rest first. I'll open the gate first."

The young man opened the stone which he said was the gate and saw a different world that was bright in the afternoon. He carried the wet Sonia to a house that wasn't too grand, but could still be called a nice and tidy house. Sonia was placed on a clean bed covered with a thick blanket covered with white down.

"You still haven't introduced yourself."

"Not for the time being, but when you have met the Red Lady I will tell you my name."

"Who is the Red Lady?"

"Cheer up, you can definitely find out for yourself."
