'A self-centric Female Lead, lost-in-love Male Leads, and useless extras who will die. On top of it, this world will not be here for long because of that ancient threat. So, what should I do now?'

What kind of world was a world of Female-Oriented Fantasy romance? One filled with tinted glass and roses? Life should have been easy here, right? Wrong! Layla had read this book before, and she knew what happened.

"Those useless leads left this world in a shamble! I need to do something about it before it gets destroyed. If I am going to live here, I need to ensure this world stays alive long enough.  Who has time for romance when the world will end soon?"

Her goal was set, and her life was laid out. Layla was going to use whatever she could to secure her second life. 

Everyone was a useful piece from here on, and Layla used them well to achieve her end goal. This might be a world based on a fantasy romance, but she would ensure it would not repeat it's ending.

Yet, she remained firm in her resolve. His presence was a threat to their safety, and they couldn't afford to let their guard down.
