SEE ALSO: Choi Hyun Wook's agency responds with 'no comment' after the actor accidentally posts a photo showing his nude reflection on SNS

She wrote on Twitter, "To all my fans whom I love... First off, I'm sorry that I'm making things hard and painful. When I think about the confusion you all must have experienced due to the various stories despite it not being my intention, my heart hurts more. 

I thought that I needed time now to recharge and reorganize myself, so I will be leaving soon for training with a plan that isn't set for too long of a time. I will try my best so that time period will not go to waste, and get ready for the day when I will meet you all again. I want to think over agencies calmly, so as I'm not hurrying, there is nothing that has been decided on, but if something is decided on later, I'll deliver the news to you first.

I'll gain strength from the support of all of you who always cheer me on, and do my best to learn and return. Wait for me."
