Kang Sae-byeok | Player 067 ⁰¹

You had entered the games because of the debts you had, most of them were from your father, who when he died left them to you, plus you had to pay for your younger brother's school so you entered the squid games where you met Sae-byeok, they instantly became friends and very close.

Now you were at the games having breakfast with a girl you bumped into and accidentally knocked over her food, the least you could do was invite her to eat with you, right? That's what you did and now you're eating with Ji-yeong with whom you got along really well, you joked, laughed and talked. Sae-byeok saw all this and didn't like it, he saw from afar how you were with Ji-yeong, who upon noticing his gaze murmured to you.
— I think your girlfriend is jealous.
she said to which you were bewildered, you didn't have a girlfriend, she gestured with her head for you to look at Sae who looked away when you turned to look at her, when you denied that you were a couple Ji-yeong replied
— I don't know, but you better go with her.
