Yuuri is a Japanese singer-songwriter known for direct, emotional ballads such as Dry Flower and Betelgeuse, and Merry-Go-Round follows that same intimate style. The title image of a carousel fits the song's circling feelings of love, regret and returning to the same person. Short excerpts began circulating on soundboards and in fan edits because the vocal swell is instantly recognisable even without the full arrangement. It remains popular with anime and J-pop listeners who use the clip to give ordinary moments a tender, cinematic weight.
