Was there a novel where the male protagonist would go crazy after the female protagonist disappeared or left for a period of time?

Answer 1

I don't know if it'll meet your needs, but I'll try my best to recommend a novel that's most relevant to your description."Quick Wear: After I'm Scumbag, I'm Dead and Escaped," the author, Yu Lixiang, wrote a sci-fi space-time travel novel.

[1v1, the male lead is all alone]
Qing He wholeheartedly followed the script given by the system, but the plot was not under her control at all!
[Host, your white moonlight is back. It's time for you to push the male lead, who is a substitute, off the Celestial Eradication Stage!]
"Are you sure he didn't push me down?" Qing He held her forehead helplessly.
The System was speechless. When did the male protagonist become a demon?!
Qing He also wanted to know…
Host, take care of yourself. The system will leave first.
Faced with the blackened male protagonist, she chose to escape from the world one: Xianxia.
[In the early stages, he was a pure love brain. In the later stages, he turned into a demon lord, the male protagonist X, who used the male protagonist as a substitute. The female protagonist of the Merciless Dao Master.]
World 2: Wealthy Class
[A black man who hides his true nature/A gentle and paranoid male protagonist X a contracted female protagonist who cheated in marriage]
World 3: The Palace
[I want to rely on my father to be noble. The Prince Regent, the male protagonist, the ambitious shield, the queen, the female protagonist] The world behind will continue to add…
The male lead was a love-struck person. I just want to have sex with my wife ~
The female lead's mind was filled with the script and the plot.
Falling in love? Heh ~
It was impossible for her to fall in love in this lifetime!
Torturing her husband felt good for a moment, but escaping to death felt good all the time!
In the early stages, the female abused the male, and the male protagonist chased his wife to the crematorium. In the later stages, the male protagonist went online in the small black room and lightly abused the female protagonist.

"You don't have a heart, do you?" The man looked at the woman in front of him stubbornly. He was unwilling to be the loser of the love game.
The woman, who was being stared at by the man, smiled and replied calmly,"You've already found out."
The female protagonist of this article had no moral integrity, no lower limit, and no heart. All the acting was just for the sake of completing the mission. If it were a guy, it would be called heartless. Don't look at the female protagonist's sudden expression. Just because she looked like she fell in love with a man, she thought that she had ruined her character. She didn't write 'broken'. The female protagonist was just that kind of person...
