Thanos and Nam-gyu

You were Nam-gyu's younger sister so you lived with him until the two of you had debts and entered the squid game, thus meeting his friend Thanos. He was somewhat annoying but cute and flirtatious with you. You were talking to Se-mi while Min-su, Thanos, and Nam-gyu were together Thanos: I'll give you pills in exchange for your sister he said to Nam-gyu mockingly Nam-gyu: I used to give you free drugs! I protested, somewhat annoyed, since he was somewhat overprotective of you
