It is a 100-chapter campus youth group portrait novel, with literary redemption and two-way secret love as the main line. The transfer student Lin Zhiyu is the "Y" who is a master of online writing, but has had countless manuscripts rejected; the quiet girl Su Ying secretly writes fanfics based on him. The two met each other through anonymous messages. They came close and missed each other ten times in literary clubs, rainy nights, hospitals, and under cherry trees. When the vest peels off and public opinion hits, the boy becomes ill and runs away, and the girl grows up to become an editor. Three years later, he returned with his last book "Chapter 101", with an open ending that hid "I love you" in readers' hearts.
