In high school, Lan Feichi and Qi Shu fell in love. Nine years later, the two met again at Qi Shu's wedding. Lan Feichi saw Qi Shu's ordinary desolation and felt guilty. Later, Lan Feichi accidentally entered a magic watch shop that can transport time and space and returned to the high school era with the pocket watch donated by Qi Shu. Lan Feichi, who has returned to the past, has done many ridiculous things to change reality, but each time the ending is much worse than the original. When Lan Feichi returned to the scene of their first encounter, he decided not to meet Qi Shu again.
Sorry, but for now we weren't able to find movies like Back in High School.
