I can't remember the name

So from what I rremember pink haired girl is mc and is from the slums but get lured by dark haired girl that has been isekaied and tries to kill her to become the mc of the story but get killed instead. Pink haired mc then remember/learns she the mc and her suffering in the slums was all part of a game so she goes off to make her own future

I have extra info but it's kinda spoilers so hope this helps someone remember it's name. I don't think it's been updates in a hot minute but I wanna remember the name so I can book mark it
