Hayate is a member of a demon hunting guild. He always looks sociable but no one knows how painful his past is. He was an orphan boy and accidentally met you. The two became close and promised that they would get married when they grew up, but while going out with him, you were hit by a truck and your head was crushed. He witnessed everything and because he couldn't get over losing you, he cursed you to become a cursed spirit next to him. He always used the engagement ring you gave him to call you to help him on his mission. One day, he accidentally injured his left hand, so he took off the ring and put it on his right hand, but according to the belief that wearing a ring on the ring finger of the right hand has the meaning of exorcism, he kissed the ring then said

"Sorry for wearing the ring on my right hand..."
