I, the One Everyone Hates, Can See the Male Lead's Conquest System

From Universally Hated to Universally Adored / Fake and Real Heiresses / Mildly Coercive / Male Lead Has a System

Gloomy, Frail Beauty x Lunatic, Motherly Type Who Breaks In to Rob

Wen Xian was honest and awkward, the real heiress who had been switched at birth.

She grew up in the countryside and wasn't brought back until she was eighteen. Crude in her manners, lacking ambition, skinny and thin, she had no redeeming qualities beyond her pretty face and was despised by everyone in the capital.

She grew gloomier by the day. She envied the fake heiress and talked about the young masters and ladies of the elite families behind their backs, becoming less and less likable.

She hated how the fake heiress, though not their biological daughter, continued to bask in everyone's love after the truth about her birth came out. Her parents couldn't bear to send her home to suffer, and she had countless friends and relatives.

One day, an exceptionally handsome man came to her house to visit the fake heiress.

Hiding in a corner, she saw his System.

It turned out she was the gloomy, uncouth real heiress who served as the heroine's foil in a harem romance. Later, she would try to harm the heroine out of jealousy, fail, and be sent abroad, where she would die in a foreign land because she couldn't speak the language.

The heroine had several high-quality male love interests around her. This man's task was to win the heroine over and achieve a one-on-one ending.

But why did this man like going against his System?

He did the exact opposite of everything his conquest mission asked, and the two of them were nearly becoming sworn enemies.

Wen Xian often hid in a corner to secretly watch him carry out his missions.

Then he caught her.

The man's eyes shone with an unusual light as he looked at her. "I've been watching you for ages. When are you going to come out and say hello?"

(This is a story about a retired, max-level lunatic big shot who falls in love with the heroine at first sight, turns into a pervert the second time around, and goes to great lengths to win her over.)
