On the first day of his second year of high school, top student Shen Juan saw transfer student Lu Youyou tiptoeing into his desk in the corridor - lemon-flavored, which was exactly the same as the package sent by the girl from the mountainous area whom he had anonymously sponsored three years ago.
He acquiesced to her secretly copying his notes, but found her altered library card in the library: she had left comments on every book he had read. When the dean confiscated her diary on the grounds of "puppy love", Shen Juan used her Mathematical Olympiad medal to guarantee it, and found that it was full of problem-solving ideas - except for a sketch of his back when he was playing ball hidden in the middle page, with the words "I want to be admitted to his university" written on the back.
In the last subject of the college entrance examination, heavy rain washed out the circuit, and the deer trembled in the darkness. Shen Juan suddenly raised his hand: "Teacher, I want to submit my application."
He walked to her seat in the dark and squatted down: "Now, I started liking you ten minutes earlier."
The moonlight passed through the rain curtain, illuminating the little fingers secretly hooked under the two people's desks, and the check mark drawn on the back of the test paper at the same time - it was the secret code they agreed on at the mountain summer camp six years ago.
