On February 9, Elefun Entertainment stated, "She's completed a meeting with the 'Return' producers. However, her casting in the drama hasn't been decided. The negotiations are continuing, but Park Jin Hee's thoughts on the matter are what's important. It looks like we'll be able to figure out whether she'll be cast tomorrow."
As previously reported, Go Hyun Jung is leaving 'Return' after her confirmed conflict with the director. Though it's been said the series will continue with Choi Ja Hye written out of the plot, it looks like it's possible there might be a replacement.
Stay tuned for updates.
