During a strange trip, Wei Le unexpectedly traveled back to his high school days, only to find himself in the body of Zeng Linhao. Faced with such a change in identity and the mysterious disappearance of the original owner, he made up his mind to follow the clues in the diary to find the "sea" with profound meaning and help Zeng Linhao make up for his past regrets.
Thanks to Wang Yue's help, he found the symbolic sea. But in the process, Wei Le disappeared, as if he had never existed. Among everyone's doubts, only Wang Yue believed and supported him. Through unremitting efforts, the two uncovered a series of mysteries: It turned out that Zeng Linhao and Wei Le were both projections of his past regrets. Their disappearance symbolized that Zeng Linhao had let go of his past obsessions and accepted his true self.
This experience made Zeng Linhao develop deep feelings for Wang Yue, but he never realized that all this was just a plot carefully planned by Wang Yue. When Zeng Linhao woke up again and returned to the day he traveled to Sanya, he stood on the beach again, full of doubts in his heart. However, the appearance of Wang Yue answered everything - he was always by Zeng Linhao's side, silently helping, hoping that Zeng Linhao could get over the regrets of the past. In the end, the two met honestly and moved towards a future together.
