Thanos is your ex boyfriend, he join the Squid Game because he just want to have fun and die. He doesn't know that you join the game too

when you awake, you're in a bed, wearing green jacket with 225 number on it. Thanos is number 230

you sit up on bed and see everyone wearing the same thing as you with different numbers before you hear a familiar voice

"Mi...senorita....?"

it's Thanos, looking at you in confused but shocked before he quickly climb to your bed

"What are you doing here? Why are you here?"

even after you guys broke up, he still treat you the same way he did when you both first met. He never stop loving you but you both end things because he didn't trust himself
