On a rainy night, 34-year-old Lin Jinzhu was hit and killed by a truck while trying to save the high school beauty and former classmate Su Qingli, now a business goddess, and was reborn back to the senior high school classroom in 2007. What's even more surprising is that Su Qingli was also reborn from a dream and knew that Lin Jinzhu was his future benefactor. He took the initiative to hug him in class and caused chaos, which was later resolved on the grounds of a nightmare. During class, Su Qingli secretly looked at Lin Jinzhu, and Lin Jinzhu wrote a note calling her "sister", which made Su Qingli ecstatic. Before get out of class, Song Jingwen, who had asked Lin Jinzhu to be a dog licker, wanted him to buy ice cream as an inducement to accompany her to dinner. Lin Jinzhu saw this through and asked her if she wanted to use lunch money.
