Sungmin's mother Kang Kyung Hwa recently took the time to speak with The Korea Herald about the controversies. 

In regards to the boycott, Mrs. Kang stated, "I think many fans are still mad at Sungmin and I understand why."

She perceived the issue with a positive mind, saying, "The elders often say that the young people are too weak nowadays. Sungmin, who promoted as an idol for a long time, also grew up weak without knowing the world. I believe he'll become stronger due to this incident."

Mrs. Kang continued, "Not a lot of things go as planned. Same with this incident. I think it's important to accept the reality and change yourself in situations such as these." 

As for Sungmin's well-being, she said, "I think he's holding on better than I thought. He's also reflecting on his actions. Recently, he's been taking classes to learn new things and he's helping his wife."

Super Junior is scheduled to make a comeback in October as a group of 7 without Sungmin, Ryeowook, Kyuhyun, and Kangin.
