Cho Hye Jin, professionally known as Groovlu, is a South Korean singer, dancer, former member of DDDD 25 (딴따라 25) and current member of OURBIRTHDAY (아워벌스데이). She is enrolled at Hanlim Arts High School.

In 2023, she participated in the Mnet survival show "Street Dance Girls Fighter Season 2" but was eliminated in the 4th episode after her team, LACHICA, placed 6th.

In 2024, she participated in the JYP Entertainment and KBS2 survival show "The Entertainer", ranking 5th overall, earning her a spot in the resulting debut group "DDDD 25". After the show, she signed a contract with Innit Entertainment (INNIT엔터테인먼트). It is assumed that DDDD 25 quietly disbanded during pre-debut due to inactivity and the members debuting under different groups.

In July 2026, INNIT Entertainment announced her to be a part of the lineup for their girl group "OURBIRTHDAY" under the stage name "Groovlu". They released the pre-debut single "Hungry (Side A)" on July 22, 2026.
