Finnic x YN Yn is the youngest victor ever after winning the 70th hunger games at the age of 12, two years after Finnic. What happens when she volunteers for mags against Finnic's wishes and join's him in the arena. In this story Finnic is 19 I know the math doesn't Work out and that is not when he won his games but I think it would be too weird If he was 24 and yn is 16 so if you want you can just ignore the details.
