Can you recommend a novel similar to 'My Wife Fell in Love with Me'?

The main point is that the male protagonist should be the kind of person who has his own story and is at the top of the game, but because of some past events, he is depressed or sees through everything. The male protagonist is a little black-bellied, but pay attention. Since the male protagonist is asked to be deep, don't introduce me to a novel with a perverted male protagonist (the kind that can't even walk when he sees a woman... Disgust!)
I'll copy it too, but please take a good look at the copied children's shoes. It's best if there's a brief introduction. There's no most yyy, only more YY. Thank you in advance.
Say it, sweat... The main point was not that he was two-faced, but that the male lead had to be the kind of person who had his own story and was at the top of his level, but was depressed or saw through everything because of some past events.
