I became the Grand Duke of the North

Synopsis

Diasta, the sole heir of the North.
While she stepped away from her responsibilities and duties, the North fell into ruin.
If only she had been braver—could things have turned out differently?

Having returned to the past, Diasta is determined that this time will be different.

But in the past, she begins to notice things that weren’t as they seemed.

“I don’t want to see my granddaughter get hurt. That’s why I oppose you becoming the duke.”

The grandfather she once feared turns out to be overly doting.

“Well, for you, I might even give up the throne.”

And the crown prince’s “joke” doesn’t sound like a joke at all.

“Wait a moment—I’m your fiancé.”

Excuse me… why do I suddenly have the most beautiful fiancé in the world?
It’s hard not to be dazzled by his looks, but… there’s something suspicious about him.

Can Diasta protect the North this time?
And who exactly is this elegant, violet-like fiancé—the master of the Mage Tower?
