My answer didn't seem to match the description in the question. According to my knowledge of online novels, there doesn't seem to be such a novel. In most novels, the male protagonist was the female protagonist's dream lover or someone with a special relationship, not a stranger who was drugged the first time they met. If you have any other questions, I'll be more than happy to help you.

"Exalted Goddess: Demon Lord, please take this!" This ancient romance novel fitted the question. The female lead was originally a Spirit Realm High God, but she was reborn as the unfavored Di daughter of the Marquis's Residence. In order to return to the Spirit Realm, she married the idiotic Crown Prince. However, after returning to the Spirit Realm, she found that the idiotic Crown Prince had actually followed her to the Spirit Realm and even told others that she was his wife. This idiotic Crown Prince was actually the Demon Lord who had caused the female lead to be reincarnated. The relationship between the female lead and the male lead was a love-hate relationship, and the male lead looked very devilish. I recommend this novel to you. I hope you like my recommendation.

I recommend the ancient romance novel,"The Man Who Wants To Be Poisonous". The female protagonist was just a Xanthium Grass that had just ascended to become an immortal and did not even know how to ride the clouds. However, before he could savor the taste of being an immortal, he had offended the First Prince of the Heaven Realm. In order to atone for her sins, she descended to the mortal world to help the crown prince of the heavenly realm overcome his tribulation. However, she only wanted to go home and be a little vixen, but she was forced to pretend to be a man to seduce the Crown Prince. The plot was fictional, so please don't imitate it. The female protagonist was a demon in this world and had also gone through the tribulation. After that, she had been following the Demon Lord. I hope you like this fairy's recommendation. Muah ~😗
