This marks her debut as a musical actress. As Joo will be on a musical stage for the first time, she said: "I'm excited to take my first step into the world of musicals. It's only the beginning, and as it is a leading role, I'll be rehearsing harder than anyone else to create an amazing show. I'll do my best to show a different image from singer JOO as musical actress JOO, so please give me your support.".
On October 31, 2012, JYP announced that Joo has been selected to take on the role of Brenda in the new musical of Catch Me If You Can scheduled to have its first performance on December 14, 2012 and final on February 9, 2013. Other prominent stars such as Girls' Generation's Sunny, CSJH The Grace's Dana and Oh Sang Eun have taken turns to take on the role Brenda previously.
On March 5, 2014, it was announced that Joo was selected to join B2ST's Yoseob in the musical remake of Full House, which is scheduled from April 11, 2014 to June 8, 2014. She joins the current cast of Full House, which includes VIXX's Leo, A Pink's Jung Eun-ji, Kim San Ho, Seo Ha Joon, and Kwak Sun Young.
Through an interview, she shared her thoughts and experiences on living as a musical actress, which is a career quite different than the one in her past. She said: "I've been enjoying performing for the musical Full House. I've been watching other musicals and taking lessons on my days off."
She also explained on choosing the musical Full House when she could have chose to return through a drama which tends to be more popular through the general public, as well as the reason she chose Full House when there are countless musicals to choose from. She revealed: "It was a drama that I really enjoyed watching as a student. I was also attracted to acting as ‘Han Ji Eun,’ which became so charming after Song Hye Kyo sunbaenim acted it out in the drama. Of course I really liked the numbers too. Also, unlike Catch me if you can, the female character has a bigger role in Full House. I felt pressure to be leading in the musical but I’m also happy every time I’m on stage because it has a cheerful storyline.”
She also revealed her hopes of wanting people who come to watch Full House would see her as 'Han Ji Eun', not as singer Joo or actress Jung Min Joo which would make her the happiest.
2015–present: Cry & Blow
In January 2015, Joo's contract with JYP Entertainment ended. In April, it was revealed that she signed an exclusive contract with Woollim Entertainment.
