Even though the harsh reality feels like living as a beggar, to think that the end would be death from overworking!
If it’s going to end like this, I should’ve been in a lot of relationships, but wait,
oh my... who are you in the mirror?

I’m a little flustered but this body… it’s really pretty!
It feels like I’ve been transmigrated into a romance fantasy novel.
Since I’m already like this, should I enjoy the romance while I’m at it?

“But which novel did I get transmigrated into?”

I’ve read dozens of books where the ‘Northern Duke’ and ‘Childhood Friends’ exist,
I’ve read so many with a black-haired male lead and a blonde female lead,
Ah~ I don’t know!! For now, let’s start by conquering the male characters!

“I already have a promised marriage."

“I volunteered for the Western Guard. We won’t be able to meet for several years.”
What is this, is this really a romance fantasy novel? Why is everyone running away?!
In the first place… was I really transmigrated as the female lead?

What kind of novel is this!!!!
