“Squid Game” season 2 remains unofficial although the ending and a lot of plots in the episodes suggest there is a lot of twists to work on.

No less than “Squid Game” director Hwang Dong-hyuk is aware that there is a lot of story angles to work on. And the ending which saw Gi-Hun (Lee Jung-Jae) not boarding the plane to the United States is at the top of the list.

Dong-hyuk admits that season one of “Squid Game” left an opening, closure for now. Gi-hun’s decision not to board the plane sent out mixed messages. That included pointing out how one should not be dragged along by the competitive flow of society and move on.

For now, nothing is set in stone and if there is a “Squid Game” season 2 in the works. But the fact that the South Korean-produced flick drew over one hundred million viewers could be more than enough to inspire Dong-hyuk to buckle down to work.

The case of Gi-hun may not be the only one that Dong-hyuk can work on. It could be a prequel of sorts on Gi-hun or touch on other mini-stories that were not addressed.

There was that one about the police officer and his brother, the Front Man. That is a storyline that could make sense as part of “Squid Games” season 2.

If not that, there is that one about the recruiter in the suit who plays the game of ddakji with Gi-hun in the very first episode.

But overall, there is perhaps no other question in the mind of “Squid Game” fans on why GI-hun decided not to get on the plan and turn back. Does he plan to face the people behind the games?

The possibilities are endless. But none of this will matter unless a second season of “Squid Games” is formally announced.
