After Passing Through the Book, Everything Is Wrong with the Yandere Heroines

Traveling to an unorthodox book, the heroines are not normal people, and all of them are yandere. Duan Nuoyu, as a beautiful boy, has no idea that they are going to catch him. He only wants to save those female characters with tragic fate. But Duan Nuoyu didn't know that he had already been targeted.

They want to keep the person they love for themselves, and no one is allowed to get close. If one of them fails, they may... Come over with a knife. "Hey! Why have you turned into a snow girl?" "I... Go, why are the vampires here?" "Holy crap! You... How are you a succubus?" Duan Nuoyu's hanging heart finally died. The cold and beautiful teacher, the big sister with a mysterious ring, the sinister perverted royal sister, the innocent and cute little white school girl... [Snow Girl] [Succubus] [Vampire] [Fox Demon] [Ghost] [Zombie]... Faced with these impending dangers, how should our hero save himself? (Yandere article, very concentrated, biased towards daily life)
