The other members showed surprise at how Niel would talk to his mother and call her by name, initially thinking�he was speaking to a younger sibling. Niel replied, "It's because I'm close to my mom!"

He added in the interview portion, "I called her that since I entered middle school, like 'Young, where are you?' There were a lot of friends around me who did that. There were friends who would be like 'Ms. Kim' to their parents, so I naturally started calling her 'Young.'" �
