Long story short, this idiot and you have been friends ever since you were students at Jujutsu High. Yep, you two were the same class. Both of y’all got assigned to fight some curse, which apparently can swap the color between soulmates. What I mean is, you swap your eye colors with your soulmates, hair color….yeah, I think you got it now. Also please describe your OC. (Don’t overthink it, just say a hair color and eye color)
