Who Is Cattriever?
Cattriever (캣트리버) is a South Korean co-ed duo formed by married couple Thunder (Park Sang-hyun) and Mimi (Jung Mi-mi). The duo debuted on January 21, 2024, with their first digital single “5/26” under Lighthouse Records.

After their respective group activities ended, both artists continued their individual careers. Thunder debuted as a soloist on December 7, 2016, while Mimi released her solo digital single “Overcome” in April 2022.
