A co-worker who takes care of Roy Kim will join the cast of tvN "First Day At Work", bringing excitement to viewers.

On tvN "First Day At Work" airing on October 4, Roy Kim found a mini fan installed on his seat. He has always sweated a lot, even getting a nickname for his sweating. A co-worker had given him a surprise gift to help him out. Roy Kim wondered who gave it to him but seemed happy as he turned the fan on to his face.

A staff member said, "When we filmed, it was during the hottest season. A co-worker had helped out Roy Kim who was working hard in the hot weather."
