Precious

She's an experiment, fodder for someone else's benefit, but there's some soul transference and transmigration and a whole lot of hate, as is necessary for the curse to work, while she's trying to save the life of the characters she loves... and collecting hotties here and there, 'cause, yea, why not.

She has uncanny luck at cards, making her living through games of chance. Having been saved by someone's kindness, she hopes to repay with her own by saving a child, but a magician gets in the way and there's a time skip. The pair are looking for one another, scared of revealing the truth, but get there in the end after some inheritance drama. Cute.
