A novel in which the male protagonist is abandoned and becomes stronger and more powerful

May I ask which novels are about the male protagonist being abandoned or being very weak?
The novel that became stronger later
Unlimited Type
Whether it was the city, the game, or fantasy…will do
It doesn't matter if it's me or not
Rebirth or possession is fine, even if I get an opportunity
But don't be dumped and then get back together with the woman who abandoned the male lead.
Unless you don't know each other, like an engagement, it doesn't matter.
There should be many novels like this
I hope everyone can provide more
The more you provide, the more you meet my requirements, I choose him
desperately in need of novels
Please enthusiastically provide the book shortage
I also hope that the protagonist won't be too fantasizing If you have the ability, you think you're invincible or you're too fantasizing
I don't have much time to come up, so I'll get to the bottom of it soon
I've seen the fight and the forbidden fruit
Can you provide more?
It's fine if you're not abandoned, but at least the protagonist is a coward
Was there any more powerful ones?
Possession, future technology
I'm really in a book shortage
