This was so disturbing I actually ended up liking it. The story was clear and to the point, I really appreciate author didn't make it unnecessary long. There's no way in hell I support this kind of relationship though so don't get me wrong. But this story was something so devastating and crushing that I couldn't help but admire the author for the work they've done. From the storyline to the message, everything is so simple yet complex.
