Is this a stretch?
Now we know that in season 2 the Front Man (Hwang In-ho) doesn't go by that name, because he knows doing so Gi-hun could probably find out that he's Jun-ho's brother, which then Gi-hun would know he was apart of the game before. So he goes by the name "Oh Yeong-il", now it is common for people in Korea to have the same last names, but "Oh" and "il" sound very familiar to Oh Il-nam. Could this mean maybe that could be name of Il-nam's son? Or maybe the Front Man came up with that name off the top of his head? Idk, just thought it was something fun to think about
