In a class called "Appreciation of Tang and Song Poetry", Yu Ming, who was typing code, met Lin Yuqing, who was talking about poetry. She interprets Li Shangyin's private sorrow, just like the moonlight awakening his sleeping poetic heart. The tender lines of poetry are handed out, and the red pen annotates back and forth, and the throbbing spreads silently between the pages. The warmth of sharing an umbrella on a rainy night is hard to beat due to the difference in status and the cold eyes of the world. A turmoil to protect her made her trapped in a whirlpool, and she pushed him away cruelly, leaving her sighing that "she can only watch from a distance".
> But Yu Ming's love is the courage to jump into the autumn water. He was not afraid of rumors and made a promise to "wait for you". Moving to a new world, jointly writing to answer doubts, his talent was finally recognized. The stern father saw the truth between the lines. From the podium to life, they used their time to write each other the most touching lines of poetry in their lives - the moonlight is eternal, the jasmine is fragrant, and the code and the soul of poetry finally get married.
