The thing is if the actress was male and the MC was female, he'd end up being the creepy guy cause he'd be constantly showing up at her place and disturbing her even when she says no.
Bruh... I don't even know what this girl is doing but, personally, I would just poison everyone and watch them die. The reincarnator person said she'd be in a loop of reincarnation if she failed anyway so might as well get revenge for the next 6 or 7 lifetimes.
I know she thinks she can change her brother with love but he's still sus to me
