This I what I've thinking, the possibility of multiple players or even the possibility of Bada originally being an npc character
I also think that maybe everyone on that game has been a player before, each of them had a cassette before, but maybe they all escaped the game and the game restarted with them being a npc again. Since in the last game we saw, one of them escaped and he turned to a npc, or Bada’s cousin remembering about the casette…but they probably all played poorly. Everyone except Bada.
Maybe Doha was the first player and he knows a lot more but now its invested on Bada and acts like he is clueless. Maybe the Doha that Bada saw was also trying to get different endings before or just got bored from the loop. I also think that Bada knows sth is different about Doha, thats why he accepted to have sex with him, in order to gain sth.
