Fifteen years ago, the prestigious Marquisate of Dilivia was falsely accused of "treason against the state" and annihilated overnight.

Her father was executed, her mother succumbed to illness, and her brother went missing. The only survivor was──Lady Liana.

Infiltrating the royal palace under a false identity, her sole purpose was clear.

Revenge against the King, her family's enemy, and his son, Crown Prince Leonard.

While playing the role of the "ideal Crown Princess"──beloved and trusted by all,

Liana quietly and surely corners the royal family.

And then comes the day of the annulled engagement──

Identities revealed, crimes exposed, and those who fall.

This is the story of a lady who feigned love and reclaims everything.

I was never in love with you.──I was only smiling for revenge.
