Emma Swan is new to Storybrooke, and starting her Senior Year at the local high school. Being the new kid in school is nothing she isn't used to at this point, and she just wants to get through the year, and get her diploma, if she lasts in Storybrooke that long that is.
Killian Jones is 23, and starting his third year of teaching at Storybrooke High. Even though he's a young teacher he already has a reputation for being a hard ass, which is exactly the kind of reputation he wants among his students. The last thing he needs is for his students to think that he's their friend instead of their superior.
Determined not to look foolish, Emma refuses to look at a school map, and ends up late for her first period, Math with Mr. Jones... it's a rocky start to a relationship that forms between student and teacher.
