Actually, I'm a Second-Generation Rich Kid

A poor young man receives support from an old man and turns his life around. He keeps honing himself along the way, only to discover that the old man's generosity comes with a huge price that must be repaid.

This is more than just a crude power fantasy with face-slapping. The protagonist is smooth on the outside but principled within. He uses his intelligence, wealth, and eventually the abilities he has trained to win over one follower after another with his personal charm, achieving his goals step by step.

The book vividly depicts both its grand scenes and the characters' inner thoughts, making it well worth reading and revisiting.
