Is there a novel with a narcissistic main character that I can recommend?

Yes, I recommend "My Heroic Spirit Summoning System is indeed problematic." The main character did not get a cheat at the beginning of the game. Instead, he transmigrated into a girl. However, she was unwilling to be ordinary. With the help of the system, she created her own money ability and eventually became a money controller. The protagonist was very narcissistic and kept boasting about his heroic bearing and super abilities. I hope you like this fairy's recommendation. Muah ~😗
