In the Ihwawon Guesthouse in Hanyang, lived three scholars as beautiful as flowers.

The cold martial artist Kang San, the aloof scholar Jeong Yu-ha, and the sly libertine Kim Si-yeol—together, they were known as the "Flower Scholars of Ihwawon."

"But who, may I ask, are you?"

"Me? I am none other than the owner of Ihwawon."

Yun Dan-oh, a bold woman born and raised in Ihwawon. People called her "the Flower of Ihwawon."

A guesthouse where both the owner and its aspiring scholars are anything but ordinary. An unexpected incident shakes up their spring—

"If you find that person, the debt of Ihwawon will be cleared."

"Who are we looking for?"

"Yi Seol, the king's nephew, rumored to have vanished during the Princes’ Rebellion."

In pursuit of the lost royal Yi Seol, they unite!

A tale of fiery youth, fluttering coats, and the "Flower of Ihwawon," who loved and was loved by them.

The romance of four youths that will turn Joseon upside down.
