The Regent Says I'm an NPC

During summer break at university, Wei Jingchen worked part-time as a beta tester at a game company. To earn more money, he chose the highest-difficulty mode: help the “weak” new emperor stabilize the realm and raise the country's GDP to the highest of the Three Kingdoms. The new emperor was named Li Lingyou. He'd loved to play and never bothered to study as a child, and after ascending the throne, he remained as lazy as ever, reluctant to attend court. Wei Jingchen entered the game as the Regent and earnestly tried to set him straight. But Li Lingyou not only refused to improve or be swayed by either threats or persuasion, he also took a liking to Wei Jingchen's looks and repeatedly tried to take liberties with him. Beta testers couldn't quit the game at will. Wei Jingchen was so furious he wanted to destroy the world. In the end, he forgot all about proper relations between ruler and subject and got into a brawl with Li Lingyou in the bath. Li Lingyou, even as he was being beaten, wore a roguish smile and tauntingly waved the belt in his hand. “You don't want this anymore?” Wei Jingchen turned and stormed off in a rage. Later, he changed his mind. The blurb is told from the top's perspective, while the main story is told from the bottom's perspective.
