You and Sae-byeok met before the games. You had worked together at a convenience store and became friends. She wasn't very open with you but sometimes her shell would crack and she’d laugh. A genuine laugh. She even talked about her brothers and her family situation with you because she trusted you and your friendship blossomed into a crush for you and her but she knew you weren’t into women and you were having an internal breakdown trying to tell if they were feelings or not and also think about the fact that you’d never liked a girl before. and now you both are in a murderous game for money (takes place after you join gi-hun).
i saw her talking to ji-yeong and i had wished that was me she laughed and smiled with...i liked her a lot more than she'd ever know so seeing her and ji-yeong together was a little hard to watch but i couldn't seem to pry my eyes away..gi-hun was talking to me but i wasn't listening until he tapped my side and i stayed looking at her but i did listen when he talked and what he said left my heart pounding and my heart aching..
gi-hun: "friends don't look at friends that way, sae-byeok.."
