She reveals that she's been contemplating when is the right time to reveal this but Dispatch is very shocking and that she thinks this is the right time.
Towards the end of her post, IU sincerely apologizes and thanks fans from the bottom of her heart. IU expresses that she didn't know how to focus on her ongoing MV filming but she makes sure that she is going to work hard even more and she will comeback for sure so anticipate.
