Don't Panic, Master Is Here (Quick Transmigration)

(Complete. I'll write a free short extra when I have time. The worlds are unrelated, so feel free to skip around. The basic setup is in the first two chapters, but you can skip those too.) After living a second life, she can't come to terms with how different things are from her previous life. But she will never let that scumbag get away with it. Teacher Xia: Class is starting! I can help you get revenge, but you can't skip your lessons. And try not to get into a relationship while you're still in school. Reborn daughter of the prime minister: ... The child of a human and a demon has suffered endless humiliation. Hmph. Those who bully and disgrace me will pay a hundredfold. Teacher Xia: Heh. You spend every day playing around with the protagonist next door, and you fail every class. Who else should your mother beat up? The human-demon child whose villainous turn got interrupted: ... After a mix-up, the real and fake daughters were switched. She should have been the right minister's daughter, but instead became an ordinary peasant girl, constantly bullied by her family. When her identity was revealed and she was taken back, everyone fussed over the girl who had taken her place, while she herself was unwelcome. Perhaps she should never have been born. Teacher Xia: You're my student, and your fellow disciples accept you too. Come back and do a few worksheets, dear. Leave the rest to your teacher. Teacher Xia and her partner, Master Teacher System 003, bring you the complete master teacher package. No refusals allowed! Thanks to my friend for kindly providing the cover! P.S. 1. The protagonist is just an ordinary person. She hesitates, makes mistakes, shows weakness, and fails. 2. The protagonist and her students are only teacher and students. There may be some familial affection, but there is no romance, whether for the protagonist or the students. Theme: Take the responsibilities of a teacher seriously, and educate and nurture your students.
