Former Wonder Girls leader Sun (Sunye) appeared in the episode of 'Oh Eun Young's Golden Counseling Center' that aired on September 20 and revealed her thoughts on withdrawing from the popular girl group.

In the episode, Sun revealed that she had a feeling of uncertainty after thinking about the purpose of life. She explained, "When I was promoting with the Wonder Girls, there were a lot of question marks inside me. I was being careful of everything, and during that time, my grandfather and father both passed away, so I started thinking about the purpose of life."

Sun explained that "There was a misunderstanding that I withdrew because of my marriage and childcare. I thought that I shouldn't hurt the other members or cause difficulties, so I felt like I should officially put my role in order." She then said to her fans, "I want to say sorry. I didn't mean to abandon the Wonder Girls. I'm sorry I hurt you."

While many fans were supportive and understanding of what Sun went through back then, there were still a handful of netizens criticizing Sun had betrayed the group. This led to Sun posting a lengthy post on her social media explaining what had happened when she decided to leave the girl group. According to Sun, she had talked with the members, and all the members agreed with her departure.

Sun wrote, "There seems to be a lot of opinions about the story behind me leaving Wonder Girls that was told on 'The Golden Counseling Center.' So I want to wrap things up and share my thoughts." She continued, "The concerns I brought to 'The Golden Counseling Center' was about my children and not about 'Wonder Girls.' After the filming, the editing is outside of my control. I was only able to see the flow of the show after it was broadcast."

Sun elaborated, "The issues concerning 'Wonder Girls' are sensitive to me and the Wonder Girls members. There might be people who do not want to bring up what happened in the past. I want to apologize sincerely to those who were hurt by me."

She continued saying, "There are a lot of comments asking 'why did you leave?' or saying 'it's an excuse,' 'you're selfish etc. I do think this is what I chose out of selfishness. In regards to that, I already continuously apologized to the company and the members. But they agreed to my marriage decision, that is why I am living in debt with my heart for the rest of my life."

Sun then said, "I don't really have anything more to say to the people who continue to attack maliciously with reckless tone and speech. I'm not sure what more they want to hear." She added, "I made a promise during my wedding press conference that I am not retiring but will continue to sing as long as I have the voice. Somehow, ten years have passed and I got to start singing again."

She also mentioned the time she revealed she had a boyfriend on the SBS talk show 'Strong Heart.' She explained, "It's embarrassing to hold a press conference about that and from my point of view, I wanted to inform you about my marriage at least indirectly through my own mouth, not just a few lines of news articles. But that was my shortcoming in communicating in that way."

She concluded by writing, "People who are calling me a betrayer, are you calling me that because your lives have been ruined because of me or you suffered great mental shock? Then from my point of view, I can say the same thing about the people who were not there when Wonder Girls came back from the U.S. I am giving an explanation for those who support me so that they don't need to spend emotional energy on something meaningless as this."
