Looking for a manga

The story is pretty generic and simple, so basically this male MC got cursed by a spiritual being that's going to be one of the Heroines/FMC.

The curse was MC's hand and one of the FMC's hand can't be released if they want the MC to die, so they have to find a way to remove the curse.

And that's what i could remember,
