What did Eric Nam do when he couldn't understand what was being said in Korean?

Singer Eric Nam appeared on 'Cultwo Show' on May 3 where he talked about the language barrier from living in the United States for most of his life.

When asked, "How was it when you first came out on 'Cultwo Show'?" he replied, "I was really taken aback.  It's the same for me now.  That was when I couldn't understand Korean very well.  If the others laughed, I think, 'Oh, it must be funny,' and blindly followed along and laughed," causing laughter right then.

The DJs complimented him with, "If you can't understand, you could've just sat there sullenly, but you laughed along, which shows how mannerly you are."  Do... people often sulkily sit at their radio show?  Seems like common sense to laugh along with the crowd.

Eric Nam replied, "I must survive, too," causing more amusement.
