A single mother moved into the room next to the run-down apartment where I live. She has a gentle demeanor, but for some reason, she always smiles sadly. I worry about her; when I need a man's hand, I help her, and when I'm sick, I ask her to take care of me. The peaceful days continued like that, but suddenly one day her ex-husband came looking for her. I couldn't stand seeing her, the one who was injured but strong, and I embraced her wildly. The sexual passion of both sought each other.
