Sun shared a post titled, "I am greeting you after a long time", on Wonder Girls' official fan cafe on the 18th through which Sun wrote, "The course of my life became a bit clearer so I am writing this post to tell you all. I received a lot of love as a member of the Wonder Girls during the past seven years and as I traveled domestically and internationally, I experienced amazing things that I couldn't experience before. I truly thank once again my Wonder Girls members, agency family, and more than anyone else, the Wonder Girls' fans who created these precious experiences."

"After I went over to the States, I looked back on my past and I was able to take time to think deeply about the things I was curious about and the things that lay deep in my heart. Through church, I was able to spend one week doing volunteer work in Haiti and during that one week, the direction of my life totally changed. What touched my heart the most when I was in Haiti was the bible passage about the return of prodigal son."

"There were two sons. The first son received praise as he worked by his father's side, but the second son left his father's side. The father waited everyday for the second son to return as he shed tears, but the first son, not realizing his father's heart, just kept going on doing his own work. If he had realized his father's pain and truly loved his father, then he should not be just doing his own work but going out to find his brother for his father. However, the first son did not do that. I felt like I was that first son."

"As I saw the many people in Haiti who were dying, never being able to hear the gospel in the bible, I was so ashamed of myself who lived only focusing on my own success... So I decided to devote my life to spreading the gospel to those in this world who don't know about it."

"As I got married and gave birth to a child, my heart became more and more firm, and as my husband and I start an NGO for missionary, I will start my second life. My husband and I will go to Haiti this July and decided to spend five years in Haiti. The activities I carry out as a celebrity will also be for this goal. I want to thank all the fans, company family, and the Wonder Girls' members who have understood and supported this decision, and to all those who are still upset, I will ask for your understanding as I live on diligently and sincerely. Although I'm lacking, I will do my best to always greet you with a good image. Thank you."

Along with her message, JYP Entertainment has revealed that the NGO (Non-government Organization) Sun has established is called 'Whitestone Global'. She has recently shot a CF for a cafe and the money from the shoot will be used as funds to carry out missionary activities of this organization to reach out to those in need.
