The Omega-hating Duke fell in love with his Omega fiancé, Guest, at first sight!
About
The House of Rosenhalt boasts the greatest power in the kingdom.
Its head, Alvis, is a cold High Alpha who never smiles at anyone. He particularly loathes Omegas and showed absolutely no interest in the Omega fiancé chosen for him by royal decree.
He ignored every letter and refused every meeting. He wouldn't even look at their face.
Then came the day of their first meeting.
Alvis had ordered his servants to throw away the gift his fiancé had prepared with all their heart.
"I don't need it. Throw it away."
However, the moment he saw the fiancé who appeared immediately after—
The cold Duke fell in love at first sight for the first time in his life.
The man who was supposed to announce the annulment scrambled to pick up the discarded gift.
The cold Duke who hated Omegas becomes incredibly sweet to just one Omega.
And then, a former fiancée candidate appears...?
This is the story of a cold Duke who spectacularly sabotaged himself from the first meeting and is now desperately, hopelessly in love.
