TVXQ's Changmin revealed his mom is a huge fan of his fellow member Yunho and Super Junior's Siwon.

On the October 14th episode of 'Knowing Brothers', the TVXQ duo appeared as guests, and during Changmin's Q&A segment, he asked, "What did my mom say to me that left the biggest impression on me after my debut?" He added, "My mom is very young at heart. She said it because she was happy."

Changmin explained, "She said, 'I'm so glad you know Yunho.' He's very good to elders, so she told me as a joke, 'Thank you so much for being born as Yunho's friend.' My mom recently joked, 'Thank you so much for enlisting with Siwon.'"
