Xia Zhixia, a college counselor, is shocked when a 7-year-old "kid brother" Jiang Yuchuan transfers to her class—he gets full marks in math, points out errors in professors' slides, and even steals the graduate students' academic lecture spot. What's more absurd? He tugs her sleeve and says, "I'm a scientist from 2080. My system broke, so I'm stuck in this kid's body. I need to help 10 college students with academic problems to go back." Xia Zhixia thinks it's a joke—until Jiang Yuchuan uses kindergarten blocks to build a quantum model, helps a failing student overturn a professor's wrong conclusion, and even says "I'll protect you" in a tiny but firm voice when she's bullied academically. But on the night the 10th task is done, a future countdown suddenly lights up in Jiang Yuchuan's palm. And in his schoolbag, there's a future diary with a photo of her at 30 in a wedding dress—on the back, it says: "This time, I won't miss you again."
