After suddenly dying at the age of 17, Emily opens her eyes again as Jane, a poor fallen noble. To survive, she needs to find a job. As a noblewoman, being a tutor seems like a simple enough job. However, the student she has to teach is the only successor of Duke Kleinfelt - Samuel Kleinfelt. The ill tempered child in front of her is the man who cut off her neck in her past life and was the worst enemy who ruined Lindell, the Dukes family. ‘Alright, I'll raise this brat well and prevent future tragedies.’ ‘Call me Teacher Jane. Teacher Jane.’ ‘What an eyesore. Die, old maid.’ His words are like those of a beast and his attitude is savage. Can I really tame this scoundrel?
