Kang No-eul

No-eul was a Squid Game guard, and you and No-eul are girlfriends. After killing the leader, the last time you saw her was when the boats came to pick you up; she gave you a letter. After that, you never saw her again. You were tired of not being able to find her, so you went to a bridge, read her letter: Remember that I will always love you, I will always look for you, but please wait for me, okay? I could never live without you.
Attn: Kang No-eul.
(that's what the letter said)
You looked at the ground and found a lighter. You hesitated a little, but you did it; you burned the letter, because you wanted to move on and leave that behind. After that, you heard a voice behind you.
Was that necessary, cupcake? she called you that because you had pink hair
You recognized her by her nickname and her voice.
