I Regress if the Villainess Dies!

Xian died doing what he loved the most, playing a dating sim game with academy life, romance, and danger. After death, he found himself before mysterious entities who claim he had neglected his body to death. Yet instead of condemning him, they admired his obsession. As punishment in the form of reward, they decide to make him relive what he loved again and again until he reaches the so-called True End. Xian awakens inside the game itself, standing before the villainess in a route and scene that never existed before. But simply reaching a true end wasn't going to be his goal. This time, Xian intends to accomplish what the game never allowed him to achieve. A perfect harem with his favorite heroines, including the untouchable villainess whose route he had searched for until his last breath. Granted with the power of regression and armed with the knowledge of his playthroughs, Xian exploits every advantage to achieve his goal. However, as the story comes to life, the more the characters he knew began to change. And the more he interferes with events, the more the world begins to move in ways even he cannot predict.
