30-Year-old Lin Yuan was involved in a car accident on his birthday. When he woke up, he found that he was back in the high school classroom in 2008. The countdown to the college entrance examination on the blackboard, the flip phone in the drawer, and the ponytailed figure in the front row - his childhood sweetheart Su Qing.
In his previous life, he missed the best opportunity to confess his love because of cowardice, but what was waiting for him was Su Qing's wedding invitation. Now that he had to do it again, he vowed to make up for this regret. But when he launched his pursuit with confidence, he found that everything was different from his memory: Su Qing was cold and distant from him, and even deliberately avoided him.
What's even weirder is that Su Qing's notebook is filled with popular lyrics that don't belong to this era, and her phone contains game guides that won't be released until 2023. When Lin Yuan finally plucked up the courage to question, Su Qing asked with red eyes, "Did you think you were the only one back?"
It turns out that behind this reunion across time and space, there is a pain that neither of them can express. When a 30-year-old soul is trapped in a 17-year-old body, can they untie the knot of their past lives and give youth a satisfactory answer?
