Lin Yuchu and Li Jianshen met when they were students. Their childhood companionship and mutual acquaintance made Lin Yuchu the person who understood Li Jianshen best. Even though the two remained silent, they could still understand each other. Lin Yuchu was like the warm sun in winter, shining into Li Jianshen's lonely and cold world, making her feel warm in her heart whenever she thought of the time related to Yuchu for the rest of her life. It is not easy to create. I hope everyone will like this warm, beautiful and a bit sadistic story.
