And that something really caught him off guard. As time goes by he just realized that he's in love again. He is in love with a person who doesn't even exist in his world. He's in love with someone whose dimension is very different from his. He's in love with a man whose life is in the other space. Can he take the risk because of his so called love and try to chase the space between them? Can he make things work out this time or he will experience another heartbreak?
