One day, at the age of six, I, Ria Flores, snuck out of the orphanage to watch the commemorative ceremony for the Crown Prince's ascension, only to suddenly regain memories of my past life. Is this the world of "You and the White Rose," a manga I read in my past life...?

Duke William, a character in "You and the White Rose," secretly harbors feelings for the heroine, but struggles as he watches his friend, the Crown Prince, and the heroine fall in love. In the end, he sacrifices himself to protect the Crown Prince, suffering fatal injuries and losing his life. He's what you'd call the archetypal tragic love rival.

That very Duke William was my ultimate favorite character in my past life. "I want Duke William to be happy." With that thought firmly in mind, I disguised myself as a boy and knocked on the doors of the Knight Order.

"Your Grace, Duke William, your very self—I... no, *I* will absolutely protect you!!"

***Romance develops in the latter half of the story. The first half has a low "sugar content" (less romantic fluff).***
