Are there novels where the female lead is REALLY evil? Not just the usual face slap scheme then everyone says that she is "ruthless". I can read on every platforms even Chinese mtl. I’ve found a couple of them on wattpad and love them.
Then maybe: Slow Prison Life Though I May Be a Villainess, I'll Show You I Can Obtain Happiness! (anthology manga)
Remind me of japanese's spider. Oher than that just search Tag:Evil protagonist & Female protagonist and also filter out Genre:Romance + Harem
there's only a handful of evil mc's even lesser evil female mc. I know only one that fits it:The Transmigration Survival Guide that has at least one really evil sub female lead(the queen). The main female lead is extremely selfish but dumb and most other female characters are cunning and ruthless as in torture/kill not face slap ruthless. Altho i never really bother with mtl unless story is really good
