24-Year-old Lin Yanfeng is a handsome and calm new class teacher and physics teacher. What bothers him most is the flowing love letters from his students. He always uses a Möbius strip structure to burn these love letters that are like waste paper to him at dusk, until one day his daughter... A piece of writing written by the child, "I have a king, a noble and graceful person, and I meet you at this moment, which suits my heart." It became a special case among thousands of letters, and also became the most beautiful "twilight erotic poem" in his heart. However, surrounded by thorns, Shen Yunqing's love letter finally turned into ashes in the dusk...
The girl's writing paper was swept away by the flames in the dusk. The moment the flames started, the edge of the letter paper quickly curled up into carbonized ripples, and the handwriting trembled in the jumping halo - it was the pen that penetrated the back of the paper, "seeing the words as if they had met each other". The warmth turned into countless tiny bubbles, like countless unspoken code words exploding. This was the end of words, but for Lin Yanfeng, it was the nirvana of the soul. In letting go and suffering, he found another possibility...
"Twilight is the kiss of vacuum decay, and you are the Lorentz factor of all my time and space."
"The ashes in the Möbius strip structure are still falling, each one written with unsent love poems and unfinished physical formulas."
"Brother Ayan, I didn't like dusk in the past, but now I like this time the most, just because of you."
Purpose: Love that breaks the shackles of the world
