My name is Samuel Gasai, commonly known as Sam. I'm 17 years old. I'm 5'5, my blood type is AB and I have a twin sister, Yuno Gasai. I live in Japan. And I was born with an incurable disease, an odd emptiness resided in my heart, making me incapable of feeling anything. I had a void in my chest. But then I met him. And every thought transformed in him. I must have him.
