## Reception
### Critical response

The Korea Herald described the film as a "funny, cute, lighthearted, and leaving you reminiscent of how it used to be when you were younger", and that it "created likeable characters... everyone in the movie perfectly fits his or her part."
William Schwartz from HanCinema commented that it is "an all-around excellent movie", and wrote that the film "chronicles their love story through 2005 and 2007 and 2012, before finally ending on a twist in 2018. It is a marathon. Any of the four different eras could be a fully-fledged movie on its own. They all have strong, engaging story-lines."
Local online entertainment media TV Report remarked that On Your Wedding Day is "emerging as the dark horse of theater's summer season." It reported that the film attracts audience in all ages—teenagers, 20s, 30s and middle-age—as it depicts a chronicle of real first love; showed realistic stories and various emotions in the changing environment; and sympathized with the memories of youth.
Online magazine Cosmopolitan Philippines commented that the film "served important life and love lessons without being too cheesy or unrealistic." The reviewer also praised the lead stars' acting performance and their on-screen chemistry.
