Su Nian has lived a lonely life ever since her parents died when she was twelve. At nineteen, she met Gu Xianzhi, who was twenty-seven. From then on, Gu Xianzhi was like a warm light, brightening Su Nian’s world. He took meticulous care of her and patiently helped her through her troubles. Gradually, Su Nian grew deeply dependent on him. It was only natural that they got together. Su Nian sweetly called Gu Xianzhi “big brother,” while he affectionately called her “baby.” Gu Xianzhi doted on Su Nian. He loved watching her act cute and seeing her radiant, sun-bright smile. They shared many sweet moments, strolling hand in hand through the streets and sharing the little details of daily life. But life could not always be smooth sailing. They had their arguments, sometimes over little misunderstandings, sometimes because they saw things differently. No matter how heated the arguments became, their hearts remained firmly turned toward each other. After every quarrel, Gu Xianzhi was always the first to give in, gently coaxing Su Nian until she gradually calmed down in his arms. Once, some troubles at work left Gu Xianzhi on edge, and he spoke too harshly to Su Nian. Hurt, she burst into tears. The sight of her tears broke his heart. He hurried to embrace her and apologize, swearing he would never do it again. Seeing how worried Gu Xianzhi looked, Su Nian suddenly burst out laughing, and the two made up as if nothing had happened. As time went by, their bond grew ever deeper. With Gu Xianzhi by her side, Su Nian gradually grew up, becoming stronger and more confident.
