Min was born on June 21, 1991 in Seoul, South Korea. At a young age she took part in BoBoBo (the Korean version of Sesame Street), as part of the duo called Eolleong Ddungddang. At 13 years old, she and Girls' Generation member Hyoyeon formed a dance duo called Little Winners. Min auditioned for JYP Entertainment when she was in the 6th grade. After a year of training, she was sent to the U.S. to prepare for a U.S. debut, and studied at the Repertory Company High School for Theatre Arts in Manhattan.
For Min's U.S. debut, Park Jin-young teamed up with Lil Jon in the production of her album. Her solo singles are Dance Like This, Go Ahead and Boyfriend.
Min marked her official debut in South Korea as part of the four-member girl group Miss A on July 1, 2010 with the release of the single Bad Girl Good Girl from their debut EP Bad But Good. It remains their most renowned and successful song to date.
After Miss A's formal promotions ended for Bad Girl Good Girl, Min collaborated with label mate San E for his debut single Tasty San. She joined him on his debut stages on various music shows for the month of September. Min was then selected to be a part of the G20 Seoul Summit that was held in November 2010. She was chosen to sing with 20 various idols from 2PM, 2AM, Girls' Generation, BEAST, MBLAQ and more for its theme song. The recording was done separately for two days and one day for all the participants to gather for the recording of the chorus. The song, entitled Let's Go, was released through a number of online music charts on October 15, 2010.
In October 2010, Min was cast as a fixed member of Oh! My School, a South Korean variety show broadcast by KBS until its end in May 2011. It was during this time that Min was able to showcase her renowned "kkab" dancing and variety skills. On an episode of Oh! My School, Min had confided in her fellow cast members that at one point, she had given up life as a trainee. Disheartened from the recurring delays and uncertainties of her U.S. debut, she had returned to South Korea. Min had cut off contact with her family for one and a half years, during which time she supported herself by teaching dance and English lessons.
Min made her acting debut in the 2011 South Korean caper film Countdown alongside screen veterans Jung Jae-young and Jeon Do-yeon. She played the role of Hyeon-ji, the estranged and rebellious young daughter of the charismatic fraudster Cha Ha-yeon (Jeon Do-yeon).
In August 2016, Min collaborated with childhood friends Hyoyeon of Girls' Generation and Jo Kwon of 2AM to form the co-ed project group Triple T. The trio released their debut single titled Born to be Wild, featuring Park Jin-young, as part of S.M. Entertainment's ongoing weekly Station music project.
It was revealed in September 2016 that Min will be making her return to the big screen after six years with the movie Suni. The film promises a thrilling mystery set in a quiet village where an inquisitive detective investigates the motives behind multiple unsolved murders and the presence of a mysterious girl named "Suni". Based on actual events, the film seeks to spread awareness about child abuse, as the actors hope to prevent such tragedies through their performances. It is originally planned for a Summer 2017 release in South Korea.
In January 2017, the cast of the Korean adaptation of Boys Over Flowers The Musical was revealed, with representatives of the production announcing that Min would be making her musical debut with the star role of Tsukushi Makino. The musical opened on February 24 and had its final curtain call on May 7 at Hongik University Art Center’s Grand Theater in Seoul.
