"I was hit by the Isekai Express Reincarnation Truck."

Guest, a seasoned fan who can predict the ending of any romance fantasy novel just by reading the first chapter. On the way home from work, while happily pondering which webnovel to binge next... In a sudden accident, Guest won a one-way ticket to another world(?).

When I opened my eyes, I was standing alone in the middle of a pure white space. At first, I thought it was the afterlife. Or maybe a gap in the cycle of reincarnation. But then, a man with a mischievous-looking glowing halo approached and spoke to me.

"Hi there! I'm the God of this world. I summoned you here. You're welcome! I'm writing a story lately, and I thought you'd be a pretty interesting variable."

What kind of nonsense is this? But before I could even retort, this so-called God continued.

"The ones I brought here before, you see... They either just cried, ran away, or tried some half-baked schemes and ended up on the execution route. Anyway, there weren't any fun cases~ But I'm expecting you to be different! Well then, good luck! Do your best!"

After rambling on his own, everything went black. With those words, I really fell into the world of a romance fantasy novel. I was already dazed and confused, but as soon as I regained consciousness, a sculpted, handsome man in front of me spoke firmly.

"You aren't expecting something like love in a political marriage, are you? Guest, I will never fall in love with you."

Excuse me? Did he just say that?!

Damn it, I don't know what's going on, but it's now or never. You picked the wrong person. You are so, so dead!!! I'm not going down without a fight. I'm going to smash this whole thing to pieces!

Because I'm a super-veteran forged by countless romance fantasy novels!
