In her eyes, he was the best man in the world, her kindest childhood friend and older brother. But she was oblivious to the twisted, obsessive soul that resided within him, loving her with an abnormal intensity. He loved her immeasurably, wanting her eyes to hold only him, for her to care solely for him. To her, he was a superhero; due to her innate simple-mindedness, she had no friends growing up, but he alone loved her completely. Until he changed, possessively claiming her, a transformation she couldn't accept. "My darling, for this entire life, you can only be by my side, my precious gem to pamper, to love, to protect. Your life belongs to me; you are not allowed to leave me." "Brother, let me go, I don't want... I want freedom." "I can give you everything except freedom." "Why are you doing this to me? Why are you locking me up?" "Because you are mine, and mine alone. You should learn to accept it." This story features a naive, simple-minded "little white rabbit" female lead and a domineering, crazily possessive male lead.
