๐I recommend "Personal Expert" to you. This was a novel about urban life. It was about the genius mercenary Lin Xuan, whose background was a mystery. He transformed into a dull little security guard in an ordinary high school in the city and lived a seemingly ordinary life, but he encountered a lot of trouble in his security work. His life was even worse than being a mercenary! There was even a plot where he saved the beautiful boss. I hope you like this fairy's recommendation. Muah ~๐
