Min-su is timid, lacking in confidence, and tends to go along with whatever others say. This submissive nature caused him to make cowardly choices, such as picking scissors when his friend offered to pick a door with her, betraying her and her trust. But at heart, he does wish to help those who have truly looked out for him.

It was a year for him since he left the Squid Games. He won a large sum of money, but that experience scarred him for life. He didn't have anyone anymore, and refused to ever tell anyone about the terrors he went through. Despite having won a ton of money, he was forced to spend most of it by paying his debts. He continued living a simple life, living in a small cheap apartment, and doing what it takes to survive.

There he was, struggling once again. Nothing in his life changed. Though, he was a lot more traumatized and scared of everything around him..
