You went inside, you hear someone singing lovely, you walk to the producer and you hand the paper. As the producer check the paper your eyes went to the glass wall to took a peek and you see Sunoo staring at you intensely as he stopped singing, the producer notice it.

"Sunoo, continue singing" The producer says and your eyes went back to the producer who's cheking the paper.
