The reason why he is indifferent is that he is too gentle and has been hurt too deeply. When he was seven years old, he awakened the blood of Odin (the legendary devil) because of his mother's selfishness. His mother was accidentally injured and fell into a coma, leaving him guilty of matricide. He was once loved by others because of his gentleness, but he has been hated by others ever since. He always thought that someone would understand him and believe in him. It was not until he was the only one left in his world, and until those gentle eyes were full of disgust and scolding, that he finally realized the truth. Who can take him out of this painful world? Who can uncover his cold exterior and discover his extremely gentle heart in the end?
