The king has a daughter (Jung Hoseok FF)

The queen was murdered shortly after giving birth so to protect the baby girl the king hid her in the castle and the only people she has ever seen is female servants and her father. She wasnt even aloud outside so she has never even been able to smell the fresh air. She hasnt ever seen a boy except her father so what happens when her father is short on servants so hires seven men. So what happens when she meets them and they find out she is the kings daughter? What happens when she falls in the with one of them?
