SEE ALSO: Sun and Sohee officially withdraw from the Wonder Girls!

Unlike the impersonal and short explanation provided by JYP Entertainment, Sun and Sohee's letters were much more intimate and lengthy, giving a detailed insight into their ultimate decision to leave Wonder Girls for good. 

Sun wrote, 

"Hello Wonderfuls who I'm always thankful for! Today may be the last day I write something here as a member of Wonder Girls..^^ When I look back on the last eight years I have walked with you all, I only have things to be grateful for. I can't even begin to name all of them.. When I reminisce on the times we spent together and recall the moments every now and then in the future, the fact that you were there will be a love I will never be able to repay. The love and encouragement you poured forth for me, I will never forget! I want to say thank you one more time. There must be a lot of things you want to say. There must be a lot of things you want to ask. I can't say spill everything now.. what I wanted to say the most was that I've been very thankful all this time... I want to ask that you cheer on each member of Wonder Girls for the much cooler and mature people they have become after giving their all for three years ^^ I want to say sorry for not taking on all the responsibility and lacking as the leader! I've had priceless experiences and realized many precious things in my journey with Wonder Girls members and you all. From now on, I will live my life the best I can as a mother and wife. You won't be able to see me as a part of the Wonder Girls from now on.. I will come back to you to show an better me when the time is right ^^ Wonderfuls, you have always been thoughtful, polite, and patient. Please keep on sincerely cheering on the Wonder Girls as you've always done and please respect their choices and paths! I want to express my grateful heart one more time. Thank you Wonderfuls!"

Sohee wrote a much shorter letter but her sincerity was just as genuine as Sun's. She wrote, 

"Hello, This is Sohee. It's been a while. I saw that a lot of people were curious about and interested in our situation after news of Wonder Girls' comeback. I have always felt grateful that so many of you still show an interest in me and love me. I'm uploading this letter because I think it's only polite to personally give my account amid all your interest. I have ended my activities as a Wonder Girls member as of today. I have thought about [my decision] a lot and talked it over many times with the members. But I felt that it will be a detriment for the group if I pursue both singing and acting at a stage when I'm still too lacking to call myself an actress. I plan to give my all in cheering on the Wonder Girls in the future. I'm just sad that I can't continue as a part of the Wonder Girls till the very with the loving fans whom I have made the happiest memories. From now on, I will show you a better me as an actress that won't disappoint your expectations. Thank you."
