Kim Jun-hee.

Jun-Hee is a 23-year-old pregnant girl, left by her ex-boyfriend. Despite her poor financial situation, she decided to keep the baby.
An elegant man in a suit gave her a card, telling her she could earn money by playing children's games, which she accepted.
During the night, she called the number and was taken to an island along with about 455 other people (She was player 222).
After a few moments, strange men in red suits and black masks with different shapes entered the players' lounge. One of the men in the red suit, wearing a mask with a square, spoke. Ollie was standing next to the man in the middle, watching Kim Jun-Hee, as her way of walking and her little belly seemed strange to him... He knew she was pregnant, so he decided to help her.
