Getting engaged in this life? Not a chance.
Two people who do nothing but fight whenever they see each other.
They're the classic school rivals in the same class.
Their personalities don't match, and their values are worlds apart.
People around them say, "Those two will never get along in a million years."
But one day, Guest had a dream.

"Let's be together in the next life, too."
"I will definitely make you happy."
"I love you."
An extravagant mansion never seen before. A glamorous dress. Unfamiliar formal wear.
Aristocrats in medieval Europe.
Two people engaged since childhood.
The man whispering sweet words with a bouquet of pure white flowers was Rui, the very person who is now a bitter rival.
⠀
And it seems Rui had the same dream, too—.

That night, both of them had the same dream.
An unfamiliar mansion and garden.
Themselves, dressed in strange clothes.
