“Would you give me the honor of having the last dance with you?
“I saved this song to dance to together.”

Yoon Do-hee, who ended her life as a fool in modern times, is possessed by the villainess 'Deborah Seymour' in the 19+ reverse harem novel 'Swallowing the Black Knight'.
Having discovered the comfort of living as a villainess, Deborah vows not to touch the heroine, Miya Binoche, in order to avoid the tragic ending of the original work, while also trying to improve her relationship with her father, the Duke of Seymour.

The story that unfolds in Volume 3 is a splendid spring flower festival.
Everyone expected that 'Miya Binoche' would be chosen as the flower of the year, but the person who took center stage was surprisingly the male protagonist 'Isidor Visconti'.
He offers Deborah a partner for the Spring Flower Festival, and Deborah, who has no partner, accepts on the condition that he conforms to the desired dress code, despite her doubts, thinking, “Why would you do this with me?”
Isidore prepares accessories, costume colors, and even the concept to perfectly match Deborah's, leaving her in awe. The two of them immediately capture the attention of the festival... Who will be the flower of the year?
