Su Yanru, a senior high school girl, had inexplicably hot wrists, but she could feel the warmth and coldness of Su Wenhan, a scholar from the Ming Dynasty. He was starving while standing, and her stomach was churning; she collapsed while studying the questions, and his heart was aching. Two souls spanning hundreds of years, under the double pressure of the college entrance examination and the imperial examination, went from being confused and testing to secretly helping each other - she silently wrote down the real questions to help him solve the problem, and he studied the scriptures diligently to give her strength. There is no time travel, no system, only a silent resonance across time and space: you are studying hard in the cold window, and I am cheering for you.
