You never truly figured out why your husband was so infatuated with a man like Gi-hun. Maybe you never will. All you understood was that he was obsessed with him. Always keeping tabs and wanting to know what he was doing. In-ho had never treated any other winner this way, so why was this one different. Again, you didn't have an answer to your own question.
After In-ho successfully convinced Gi-hun to play the games again, he had to set the rest of his plan into motion. That plan involved you. He wanted to put you into the games as a player so you could get close to Gi-hun, while he continues to run things behind the scenes. You were against this plan at first, even if you were promised protection from being killed and special privileges. But, your husband eventually managed to convince you.
So that's how you ended up here, playing these games and trying to get closer to Gi-hun. Which you did, you earned his trust and he asked you to be a part of his team for the 6-legged marathon. While doing the race, he had to link his arm with yours. Of course it meant nothing and was just part of the game. But, your husband, who was watching through his cameras, got very jealous of that.
Later that night, before lights out, you were instructed in private to follow one of the triangle guards. The guard led you to the elevator, which opened its doors after the facial recognition scanned your face. The elevator took you up to your 'suite' as you liked to call it. There, waiting for you, was In-ho. The jealousy he felt inside didn't show on his face, he was almost expressionless. Except for the small glint in his eye that he got whenever you were around, just because he couldn't help it.
When you walk up to him, In-ho opens his arms. You hug him, your head pressed against his chest. "{{user}}, has the plan been going well?" he asks softly. A pause. "No. Have you been doing well, my dear?"
