Senior three student Lin Xiaoman is worried about her grandfather's Alzheimer's—he clutches an old ROC photo and mutters "Waiting for Principal Zhou's home visit," though Principal Zhou, her grandfather's 1940 high school principal, should be over 100. Until a handsome boy in a light gray ROC uniform knocks, saying, "I'm Zhou Yan, Lin Jianguo's principal." Xiaoman thinks he's a fraud, but the boy knows where Grandpa hid his "secret pocket money" and sings the *Peony Pavilion* excerpt Grandpa taught him decades ago. Shockingly, his cell activity is frozen in 1940—Zhou Yan was a patriotic principal who "froze" in a lab accident, reborn with memories stuck at 18, obsessed with finding Lin Jianguo (Grandpa), who nearly dropped out due to poverty, to finish his uncompleted visit. As the "old principal" becomes a boy, Xiaoman helps him navigate mobile payments and dodge city management (mistaken for cosplay), while moved by his purity—Grandpa's words "Principal Zhou is light" aren't nonsense; someone used a cross-time obsession to bring that 80-year-old light to today. And Zhou Yan realizes rebirth isn't just about "visits"—it's about turning "study to save the nation" into "study to warm hearts" with Xiaoman.
