The DJ then commented, "I was wondering why Fin.K.L wasn't reuniting."  Ock Joo Hyun explained, "We want to keep it a mystery. It wasn't like that in the past, however. That's why when we don't perform we keep things a mystery."

She continued, "I mentioned earlier that Sung Yuri seems to be the most successful out of the Fin.K.L members. I just happened to meet up with her before and that's why I mentioned her name. To be honest, we just go with the flow."

A very ambiguous answer...
