Yu Ci from the Department of Mathematics is silent and reserved, accustomed to explaining the world with theorems and measuring everything with logic. The Chinese-language Song Dynasty is soft and romantic, using words to express feelings and viewing the world with gentleness.
They sat next to each other in the library, reading and writing, quiet and warm, from strangers to tacit understanding, from silence to concern. Yu Ci occupied a seat for her, gave lectures, and organized notes. Song Wan wrote poems for her, left a lamp, and recorded the glimmer of light.
There is no excitement, but there is a heartbeat that cannot be hidden everywhere.
Yu Ci can calculate the boundaries of the universe, but cannot measure the frequency of his own heartbeat; he can prove thousands of theorems, but cannot deduce a love.
Until she handed the notebook filled with formulas to Song Wan, the last line only contained one sentence: The direction of the heart is unmeasurable, and Lebesgue is unfathomable.
It turns out that the best love is when I protect you with reason, and you heal me with gentleness, and each other becomes an axiom that the other does not have to prove in his life.
Intention: True companionship does not require making noise, heartbeat does not need to be expressed, and the compatibility of souls is immeasurable written down by words and formulas.
