On the episode of "Radio Star" that aired on March 7, Kyuhyun was listing all of the things he did for his parents with his income. Beforehand, the members of 2AM were showing off what they did for their parents. So because Kyuhyun didn't want to lose, he revealed that he signed an affidavit of support for his father's business, which drew many eyes.

This episode of "Radio Star" was a 2AM come back special. It featured the members of 2AM, Jo Kwon,Changmin, Seulong and Jinwoon, who all have both the looks and the skills. They also showed off their exceptional variety program skills as well.

When the MCs asked what they did for their parents, Jo Kwon answered that he gave a car to his parents. Seulong gifted his parents with a house. Then Kyuhyun blurted, "I made my parents move to a 40-story apartment complex."

Kyuhyun continued, "I'm driving the car my mother used to drive and I gifted her with a new one. My father started an academy in Taiwan and I signed the affidavit of support," to everyone's surprise.

It's nice to see our K-Pop idols be good sons/daughters to their parents!
