Was this urban novel about how the protagonist became stronger through adventures?

The protagonist was very unremarkable at the beginning. His family background was not good. He did not shine in school and was often bullied. He did not dare to speak to the girl he liked, but he had a good personality. Then, through some fortuitous encounters, he would slowly become stronger…
No online games, no rebirth, no urban abilities, or something similar to fantasy...
If the plot needed it, it would be best if there was a plot where a woman dumped or mocked him.
I hope that everyone will recommend what you think is good after reading it. When recommending, don't forget to include some introductions ~ It's best not to copy.
I've read one book so far, and I think it's not bad. It's Dual Cultivation of Arts and Science.

Answer 1

😋I recommend the following two novels to you:

1. [The Strongest Personal Guard: The protagonist walked out of the deep mountains and became a powerful guard by relying on magical medical skills and overbearing martial arts.]
2. "When I'm at the Advanced Martial Arts Stage, I'll become stronger in my dreams!": The protagonist had experienced the revival of reiki. In order to become a powerful martial artist, he had gone through all kinds of tests. However, he had obtained unlimited strength from the fortuitous encounter in his dream.
