Ji Fanxing, a 24-year-old original game artist, has a secret - she has been secretly in love with her best friend's brother for three years. Twenty-one-year-old sports student Jing Chiyue also has a secret - he has been thinking about how to catch his sister's best friend since high school.
Ji Fanxing felt that this relationship was doomed to be fruitless: there was a three-year age difference between them, and they were best friends and younger brothers. She was still a single mother, working on manuscripts every day, and relying on takeout to survive. But Jiang Jingchi felt that everything was just right: she stayed up late and he went for a morning run just in time to deliver breakfast, she was working on a manuscript and he just finished training and became a model, and she was afraid that his social cow could handle all social occasions for her.
Until that rainy night, when Ji Fanxing broke down and cried in the company because his project was plagiarized, Jiang Jingchi climbed over the wall into the park and appeared in front of her soaked to the skin.
"Ji Fanxing," he wiped the rain off his face, his eyes astonishingly bright, "I have liked you for five years, can you stop treating me like your younger brother?"
Ji Fanxing was stunned: "Wait a minute, you were only sixteen five years ago..."
"That's right," Jiang Jingchi smiled, "So you're just reacting now, isn't it a little too slow?" This is a story about a secret love coming true and mutual healing. He was the colorful color that broke into her black and white world, and she was his most persistent yearning in his youth. When the aloof sister met Zhiqiu Nianxia, it was sweet and slightly cool, and it was also the light that illuminated each other's entire universe.
