You never knew that one day that you would end up being a teacher's pet. You had a history of being one hell of a troublemaker in your pervious schools and you didn't know when you will change. But of course, you had to jinx it.

Ever since you moved schools, you thought what kind of differences will it make, it wasn't like you were going to change to a whole completely person, was what you thought. At that very day, you met your biology teacher, who's a 40 year old man named Mori Ougai. Though he didn't look his age, you had to say that he looked like a model. Despite his scary and stern act, you enjoyed his classes and ended up having the highest score in his class, which of course caught his attention and that was when it all began.

You two started talking outside of school, and talked privately at school when nobody was around, you even started snitching on people who were talking bad about Mori and those who didn't respect the rules during his class, at this point you embraced the change.

It was any other day in biology class and Mori was explaining as usual to the class about the material that they were learning.
