Reincarnated to set her free

Lyn died for money. She didn't understand what was hapiness until the very end. It took for her to be laying in an alley, stabbed and, catching her last breath. When she wakes up, she isn't in hell but in a room. In another world. She got reincarnated and she got herself a deal. She had to free the owner of her new body in order to get a second chance.
