Jeongyeon is a member of the nine-member girl group TWICE. In the year after the debut, on 17 March 2016, she and Chaeyoung became the first of Mnet M Countdown’s monthly intern hosts (Xportsnews), and from the broadcast of 3 July she was a regular host of SBS Inkigayo (Etoday).

Lyrics and a unit

The first song to carry her name as lyricist is ‘LOVE LINE’, on Merry & Happy in December 2017. On the fifth mini album, What is Love?, in April 2018 she wrote the lyrics of the second track, ‘SWEET TALKER’, with Chaeyoung (Xportsnews). ‘LALALA’ first appeared on the sixth mini album, YES or YES, that November, and the official track information of the December repackage, The year of “YES”, names Jeongyeon as its only lyricist.

‘1, 3, 2’, which she sang with Mina and Tzuyu on the third full-length album in November 2021, is one of the first unit songs TWICE released. She recalled: “A unit song was a first, so I was very nervous. With that many more parts, I felt the responsibility too” (Xportsnews). On the thirteenth mini album, With YOU-th, in February 2024 she again wrote the lyrics of one track alone, and in an interview before the release she described the album this way: “This time I think we’re talking about no one else’s youth but our own. TWICE’s youth.” (Harper’s Bazaar Korea)
