Sun revealed explanation on withdrawing from the Wonder Girls.

On the September 2nd episode of ‘Oh Eun Young’s Golden Counseling Center’, Sun opened up about withdrawing from the Wonder Girls in 2015, saying:

“When we were on the road to success, there were a lot of question marks inside me. I was being careful of everything, and during that time, my grandfather and father passed away, so I started thinking about the purpose of life.”

She continued:

“There was a feeling of emptiness that I can’t explain or express. I don’t think I could fill that void even if I become more famous or rich. I thought that I would damage the members if I stood on stage with this mindset. I needed rest as much as I had been running forward without looking back.” 

Sun' Explanation

On her withdrawal from the girl group, Sun said:

“I think 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.”
