Damn, I Have to Marry the Strongest Antagonist at the Start?

What would you do, if you could transmigrate to the anime you designed? Upon transmigrate to the anime world, Owen found himself standing at the edge of the arena.

A tall, coldly beautiful figure held a staff, arrogantly surveying the crowd! At this moment, the system sounded! [Ding, please choose: 1. Challenge on stage to receive a god-tier reward; 2. Abandon the challenge and lose 50% HP!]

Challenge! [Ding, congratulations to the Host for obtaining a god-tier reward]. Nice, let me show you the power of a transmigrator! At this moment, the system's voice sounded again: [Ding, please choose: 1. Host marries the strongest female antagonist and conquers the world together; 2. Abandon the challenge and lose 100% HP!]

Excuse me??? Is there even a choice here???
