It's a seulrene fanfic. I don't remember much but basically they're in a world where I think some kind of a dystopian world and has a kind of scifi theme too and I think it was joohyun that emotionally regressed to her younger self. Seulgi takes care of joohyun because of that. Also some memorable quotes are joohyun saying the captain/director is a meanie and also when they got punished and have to work in the kitchens and joohyun was tasting the soup and got hit in the head. Please help me find this fanfic I remember reading it last year and I couldn't find it anymore and I really want to read it
