Can you recommend a doujin novel where the male protagonist kills the teacher?

I recommend Ghost Photographer to you. The male lead was a photographer, and the female lead was a detective. Although she was not a teacher, she was still a very powerful female character. I hope you like this fairy's recommendation. Muah ~😗

Of course I know! It was the book "Teacher, Come Quick". In it, there was a PK between a cute female student and a gentle, black-bellied male teacher. The plot was very interesting. I hope you like this fairy's recommendation. Muah ~😗

😋I highly recommend the book,'The Sweetheart Teacher of the National School Handsome' to you! This was a romantic youth-rebellious growth novel. It was about a girl who fell deeply in love with a young man and pursued him crazily in high school. Four years later, in university, he, who had lost his memory, began to pursue her. It was a story about a school hunk pursuing a teacher. This book can satisfy your need for a sweet love story where the male lead is the female lead's teacher, not a teacher-student relationship. I hope you like my recommendation, Mwah ~😗

I recommend "Naruto: The Strongest Teacher". The male protagonist, Iruka Umino, transmigrated to the ninja world and became a glorious ninja teacher. He was the first teacher of the nine Koba Ninjas and was also the strongest ninja teacher in the ninja world. His teaching method was also very special, which made people's eyes light up. I hope you like my recommendation. Muah ~

I'm not sure which novel you're referring to because you didn't provide a specific name or plot. However, generally speaking, novels where the male protagonist killed a heroine might cause readers to feel disgusted or uncomfortable because such plots were often seen as a manifestation of violence or hatred. If you can provide more information or plot, I will try my best to provide you with a more accurate answer.

"Rebirth: Every Confession Killed" might meet your requirements! After Ye Heqing was reborn, she realized that as long as she confessed to Zhu Heng, she would be attacked. She was very depressed.

His dream was to unite the four kingdoms and make the Song Dynasty strong. When historical figures appeared, he was already changing the course of history, and Li Shishi was one of them.
