## Early life

From a young age, Woozi studied classical music and learned to play the clarinet and other band instruments.

He graduated from Hanlim Multi Art School and subsequently enrolled in Hanyang University. In 2022, he enrolled in a Master's degree at Anyang University.

## Career
### 2015–present: Debut with Seventeen and solo activities

On May 26, 2015, Woozi debuted in the self-producing group Seventeen with the single "Adore U". He helped write and produce every track on their debut extended play (EP) 17 Carat. He has since become Seventeen's main producer along with Bumzu and is credited for writing over 80% of the group's discography as of January 2019.
Shortly thereafter, Woozi began writing for other artists as well. In 2016, he and Ailee wrote lyrics for her collaboration with Eric Nam, "Feelin'". In 2017, Woozi wrote the last single released by the project group I.O.I, "Downpour", whose lyrics received praise. Later that year, he gifted the song "Thankful for You" (지금까지 행복했어요) to South Korean singer Baekho of boy band NU'EST W, which was featured in the group's first EP W, Here. Woozi became a full member of the Korea Music Copyright Association in 2019. On October 15, 2019, Woozi released the song "Miracle" for the soundtrack of the television series The Tale of Nokdu.
In 2021, he worked with fellow Seventeen member Hoshi on the latter's song "Spider", which debuted at number five on the Billboard World Digital Song Sales chart. That year, Woozi won Best Producer at the 6th Asia Artist Awards, becoming the youngest recipient of the accolade in the show's history. He released his first mixtape, Ruby, on January 3, 2022. Its lead single, the first track he wrote entirely in the English language, reached number one on iTunes charts in at least 18 different regions, including Chile, Mexico, Indonesia, and Philippines.
On January 26, 2024, Woozi officially released the song "What Kind of Future" as a birthday gift to his late friend Moonbin, who had died the previous year.
On February 19, 2025, Pledis Entertainment announced that Woozi would be debuting in a sub-unit alongside Hoshi as Hoshi X Woozi with the release of a single album titled Beam on March 10.

## Endorsements

In October 2022, Korean fashion brand Romantic Crown announced that they had selected Woozi as their brand model for their 2022 Fall/Winter collection. In March 2023, the brand collaborated with Woozi on a second collection, which featured clothing referencing "Universe Factory", Woozi's nickname for his music studio.
