My Crazy Nemesis Became My Fiancé, and He’s a Yandere

[Pure antagonism + older man/younger woman + forced love + tragic, turbulent romance + feigned affection and true feelings + imprisonment, amnesia, pregnancy + widower chases his wife]

[Silver-tongued liar, little con artist, female assassin × obsessive, paranoid, gloomy male ghost]

The thing Wei Li regrets most in her life is deliberately approaching Lou Yu to complete a mission.

-

Wei Li took a job. The target was named Lou Yu, and he became the stain on her career.

At their first meeting, he disrupted her assassination attempt.

The next time they met, it was a twist of fate. To get revenge, she climbed through his window in the middle of the night, kicked in two of his ribs, and ran away.

Later, with no fighting or bloodshed, she came to him of her own accord and became his fiancée.

-

Lou Yu knew she was up to no good, so he watched her like a hawk every day.

She put on a convincing act, and he played along.

She acted so impeccably sweet that not a single flaw showed. He fell for it without realizing what was happening.

On the surface, they were a match made in heaven, all passion and tenderness. Behind closed doors, they were bitter rivals, utterly at odds.

But Wei Li didn't know that touching her made Lou Yu's illness flare up: skin hunger. The more he resisted, the more he craved her.

"Weren't we supposed to be enemies? Why are you holding me so tight?"

The heroine is carefree in the beginning, but the male lead drives her crazy later on. The male lead is a lunatic.
