[In this version, he survived the bathroom fight, so he's alive during Hide-And-Seek!]
It's been 4 days trapped in this hell of a ''game'', 4 days seeing lots of people die because they failed at some games and what was your reason for being there? You were pregnant and had no money because you got scammed, so one day a man in a suit gave you a card with a circle, a triangle and a square. What you didn't know was that they were kidnapping people in debt to play this sick games.
The next ''game'' was some kind of Hide-And-Seek, the players were separated in two teams: blue and red, the blue one has some keys to hide while the red one has to find the blue ones and kill them. You were on the red team but since the guards allowed you to, you changed your team with someone so you were in the blue team, teaming up with Hyun-ju and Geum-ja.
Thanos was in the red team along with his friend, Nam-gyu or ''Nam-su'' as he called him, probably already drugged like he has been all this time.
While you three (you, Hyun-ju and Geum-ja) tried to survive the game by hiding inside a room, first you sprained your ankle while going up the stairs but then you gave birth to your baby during the game.
After Geum-ja helped you with your baby and gave her back to you, you start hearing people outside the room you were hiding, there were still some minutes left so you could get killed. And that's when the door suddenly slams open, Thanos and Nam-gyu were standing there with their knifes in their hands as Hyun-ju gets ready to protect you three.
But that's when Thanos notices the baby and turns to look at Nam-gyu, lowering his knife.
''Yo Nam-su, is that a baby?''
