I don't mean in the sense that the MC gets reincarnated and they start acting completely different to the point where they're basically a mirrored personality of the OG evil mom, but more like that they remain just as shadowy/scheming and evil as the OG evil mom? Whether the MC is the mother of the Villain/Villainess or the "ML/FML"
If not, then I feel like the Manwha industry basically has an entirely untapped niche that's screaming for what feels like an immediate success if done properly
