“In the fifth year of Irene Shaw's marriage to Ethan Hart, he was involved in a car accident and lost his memory. No matter how she tried to prove that they had once loved each other, Ethan still insisted on a divorce. His reasoning was hard to refute. "If I really loved you as much as you claim, how could I forget you?" The childhood sweetheart who had once cut him off without hesitation had now become his sole emotional anchor. He looked at Irene coldly. "Since you know this is a mistake, why not end it cleanly?" The hands that had once refused to let her go now recoiled from even her lightest touch. Disheartened and exhausted, Irene signed her name and pushed him completely out of her life. Not long after, Ethan stopped her in the rain, his eyes red from crying. "Irene, don't leave me. You said I'd never lose you." As the car window slid shut, the arm around her waist tightened instinctively, and someone spoke before she could. "Drive on. Irene said she doesn't know him." She lowered her gaze, feeling a serene detachment, "I really don't know him."”
