It's hard to be invested in a story that provide absolutely no challenge to the MC. It's 25 chapters of a huge revenge wankfest following a one-track-mind Mary Sue and 3 chapters of pay off that feels so underwhelming because the antagonist is at best brain damaged, at worse a cartoon character. "Let's get married" she shouted to someone she never met, AFTER he made clear she was not going to have a good time.
It's also super repetitive. Every chapter has the same plot: MC manipulates people, smirks, succeeds, smirks, gets praised, smirks, wanks/schlicks Emi like it's her last day on Earth, repeats. Sometimes, for a change of pace, she kill Gods. Thrilling.
Even the cover art is on the level of a reddit argument. "Too late. I already depicted myself as the calm Chad and you as the pink Wojak".
How is that the best rated villainess story?
