Shidou Yukito’s mornings are always busy. Waking up before the sun rises, battling against the cold air and temptations to go back to sleep, every second is too valuable to waste.

A regular day, regular people, and Monaka’s regularly forgotten lunch box, Yukito is content with his peaceful normal life. That is, until his estranged father died.

Out of the blue, a woman who claims to be his father’s secretary informs him of a tremendous debt his father has left behind with his legacy and wants Yukito to succeed in his place or else Café Soleil, along with their house, will be subject to bankruptcy claims. A debt that can’t be cleared in any reasonable amount of time, let alone the deadline is in less than a year, Yukito’s only choice is to marry his fiancée from the Corangrane Kingdom in Europe, a descendant from the noble Soleil Family. And that fiancée is coming to meet him tomorrow.

And as if that wasn’t enough, the first words coming out of her mouth was:

“So you are my fiancé. En guarde!”

Will Yukito be alright? The fiery duels between unshakable wills over marriage, the battle royale has begun!
