Xu Xing has been Cen Wan Ning's sister for many years. She wore a mask and lurked on the front line to take pictures. By chance, she twisted her leg, but she was able to get close to her idol. So she simply played the role of a little white flower, trying to leave a good impression on her idol, but she was defeated by the idol's "senior sister". It turns out she still remembers.
Much later, she found her own photo in her idol's photo album, and suddenly realized that he not only remembered her, but also had planned it for a long time.
Intent: Two-way secret love
