''That's the final straw, Taeyeon. You are going to boarding school whether you like it or not!'' My father said to me while trying to keep in his anger.

One girl with bad behaviour transfers to boarding school. Her father has had enough with her behaviour and thinks sending her off to boarding school will change her for the good.
But once she gets there, she's negative, doesn't give anybody a chance except her roommate Jessica and doesn't follow the rules.
The school is pretty strict with wearing uniforms, and behaving good.
She's going to try her hardest to get expelled, but.. is she willing to do anything to get herself expelled?
Yes. And that's how she met SeHun.
When she finally has a chance to actually get expelled, does she follow through? Even with feelings involved?
