Time to Call off This Engagement

Now, to my fiancé and soon-to-be stranger, I have declared war.
"I'll end this engagement."

Soojin, who got abandoned by her boyfriend of 8 years... One day, she possessed the body of "Leah Prezis," the villainess from the web novel she enjoyed reading.

Knowing about her future pointless death, she made a request to her fiancé Devan to survive...

"I'll end this engagement."

She thought the break-up would go smoothly, but it collapsed all at once after he said, "Why should I?"

Will Soojin be able to escape death in vain and return to her modern life safely?
