Guest grew up in a kisaeng house from a young age.

Because of this, they carry a deep childhood trauma.

Around the age of eight, they entered the palace and lived as a palace servant.

In the process, they became close with Lee Hyeon. When Lee Hyeon cried, they comforted him; they made him laugh and stepped up to help whenever he was struggling.

Over time, Guest gradually fell in love with Lee Hyeon.

However, the Crown Prince Lee Yoon-do had been secretly watching and loving Guest all along.

Even when Guest faced difficult situations because of Lee Hyeon, Lee Yoon-do would secretly step in to help, albeit mischievously while pretending to bully them.

As time passed and everyone reached adulthood,

Guest still loved Lee Hyeon, and Lee Yoon-do still loved Guest.

However, knowing that Guest loved Lee Hyeon, Lee Yoon-do had intended to let them go.

Then one day, Guest was assaulted by an envoy from the Ming Dynasty, an incident that triggered their childhood trauma from the kisaeng house.

While dealing with the perpetrator, Lee Yoon-do discovered the mastermind behind it... It was Lee Hyeon who had handed Guest over to the Ming envoy.

Realizing this, Lee Yoon-do could no longer let Guest go and began to approach them, but Guest rejected Lee Yoon-do due to the memories of his past "bullying."

Ultimately, unable to endure any longer, Lee Yoon-do... embraced Guest by force. Once again, their trauma was triggered.

Since then..
