Since you've accepted more jobs in Thailand, the fans from other groups also came to love "Nichkhun'. You became 'P Khun' to the young ones and a warm hearted brother of your fans?
Actually, for junior idols, I just want to watch them grow. I met Twice girls when some were 11. I met Bambam when he was 13. I got to see their improvement. Right now, he dances and performs so well. I'm proud of them. As for Blackpink Lisa, I knew her via Bambam. She is very lovely and talented. In the beginning, she asked me for advices on how to make a performance more dope. I told her not to worry. You are already good. and Bambam as well. I always tell her that 'You must be a good person. Be a good girl. And you must take good care of the people around you including staff, managers and the crew.
