What did Nam Goong Min's family think about his evil, psychopathic role on 'Remember'?

On the March 10 airing of 'Happy Together 3,' Nam Goong Min talked about how happy his family was about his role as the evil, conniving character Nam Kyu Man on 'Remember.' 

Yoo Jae Suk had remarked, "Nam Goong Min's father is a school principal," and went on to ask the actor if his father was worried at all about his son's popularity.

Nam Goong Min replied, "My father was happy but my brother was the happiest. He said it was fun watching me get all worked up." 

Nam Goong Min's brother might not be so happy when Nam Goong Min brings out his psychopathic wrath upon him...
