On the March 28 episode of 'Happy Together 3', SPICA's Jiwon spoke up about the lengthy period she spent as a trainee.

Jiwon had a long history. First, she was a part of Five Girls, a group consisting originally of After School's UEE, Wonder Girls' Yubin,�SECRET's Hyosung, and G.NA. When that fell through, she was set to debut as a part of T-ara.

On almost debuting under Five Girls, she stated, "I was a trainee for 10 years. But the team didn't do so well, so I moved on to another label." After moving to T-ara, she recorded a song with the group and looked forward to debuting but unfortunately she wasn't able to debut and left the group. She stayed away from the industry for 2 years after this before she finally debuted as a SPICA member.
