After I Passed Through the Book, the Yandere Villain Became Addicted to Me!

[Through the book + single female protagonist + yandere + villain + system] Shi Yubai is a top killer who is firmly ranked first on the killer list. One day, he traveled to a female novel and became the supreme ruler of a mercenary organization. But I never expected that the original owner was actually a bitch in private. In order to return to the real world, he must prevent the villain from turning dark and prevent the plot from collapsing. But the strange thing is that the villain looks at him more and more strangely. She even tried every means to knock him down and eat him clean... - In order to complete the task, Shi Yubai kept a low profile, but people still came to provoke him frequently. Do these people really think he was a vegetarian in his previous life? Is the female lead of White Lotus pitiful? He exposed it on the spot, every word of which was heartbreaking. The hypocritical male protagonist pretends to be good? He tore it apart with every word and showed no mercy. Is the scheming supporting character plotting something secretly? He saw through it at a glance and fought back every step of the way. Just when he thought the mission had failed and the world was about to collapse. But the system's voice suddenly sounded. Bite! Congratulations to the host for becoming the male protagonist of this book. The final mission is to pursue the yandere villain Ikemi Yuu.
