Seol is just an ordinary girl trying to make ends meet, working odd jobs, crushing on her teacher and occasionally running into the hot-but-infuriating Hae Young, a local company man. Then it's revealed that Seol is actually a long-lost descendent of the emperor! What's a newly discovered princess to do?

Seol isn't ready for the truth about her family, but that's fair, because Hae Young isn't prepared to accept her as his aunt. Little do they realize that their frustrating days together are just beginning! Meanwhile, Jung Woo has issues with his ex and Yoon Joo is unrepentant for her sins.

If only Hae Young wasn't so arrogant about coaching her... and if only her mother didn't egg them on, believing them to be engaged...

Her new home is like something out of a fairytale, but between tripping in her heels and fainting in courtyards, Seol isn't quite ready to be a princess.
