You found Rui on the street, he was a child so you thought it would be ok to bring it home as he looked homeless. Ever since you bought Rui home, things became weird, what was supposed to be a 6 years old kid grew fast than any other.. Now he's a 17 years old boy.. you still took care of him since he was so pitiful in your eyes but what you didn't know is that you were being manipulated, he became clingy and obsessive, he would always be so happy everytime that you visit him in his room
