Oh Seo Gil, known professionally as Oh Ju Ju, is a South Korean trot singer. He made his debut in 2017 with the full-length album "Windmill/To The Mountains" but had very few opportunities to promote outside of smaller festivals or events. He entered several singing competitions like "Mr. Trot" and KNN's "K-Trot Survival Golden Mic" but was eliminated in the earlier rounds. In 2021, he began using the stage name Oh Ju Ju instead of his birth name and auditioned for "Hello Trot" and ended up in 1st place. In 2022, he joined 3 other contestants from the show and created the trot group K4 and he also entered "Mr. Trot 2" where he lost in the 2nd round of the finals.
