Good translation. The reason I didn't enjoy this novel is that it starts with an intriguing premise but quickly devolves into a repetitive list of all the cool cars the protagonist will drive, the ways people will fawn over him, and ultimately, how he will play cruel pranks and overpower everyone with his wealth while still winning the girl. There are no true antagonists in the story, and his actions can be quite callous at times. It reads more like a teenager's revenge fantasy.
There is barely any development of his relationships with his parents and old friends, which could have added depth and color to the plot. The main character lacks a distinct personality, and it's tedious how he uses his victories to socialize with the wealthy. Additionally, why don't these 'rich system' stories ever show the main character doing anything for charity (other than helping abandoned animals)? It's disappointing.
The overall theme of the novel seems to be that if you have money, everyone thinks you're wonderful. I wish this were a satire, but it isn't.
