He has lived in pain all his life, just because the demon is destined to suffer all his life, and living is pain. If you fall in love with someone you shouldn't love or can't love, you are destined to be unable to live without him. He can't live without him. He controls his life and his death. . . Miracle? He is a miracle in his own right. . . Oh, he is terminally ill and destined not to live past the age of 27. Why do they still love him and give everything in the world just to keep him alive? ? Dad said that he is a real demon. Living is painful and brings pain to others, right? By the time he realized it, it was already too late. He could no longer control his own life and death. . . He really loves him. Demon can only love one person in his life, only him. . . (They hurt each other and suffered for each other. Is love just about torturing each other?)
