Summer, who is quite susceptible to superstitions, stumbles upon a post on social media titled "How to Travel to Another World by Elevator" and decides to give it a try. To her surprise, she actually ends up in a parallel universe.

This bizarre phenomenon allows her to return to reality after half a day, so Summer begins living a double life—spending 12 hours a day as a serf in this other world. Initially, she uses this as an escape from her real-world problems. However, as she works the land, Summer realizes that farming might be her true calling. She starts dedicating her time in the other world to gaining agricultural experience for a potential future as a farmer.

During her interdimensional adventures, she meets Noel (Han Do-yun), who is also traveling to the other world for half a day and working a side job as a hero. Mistakenly believing each other to be natives of this other world, they enter into a contractual engagement. But little does Summer know that Noel, her fiancé in the parallel world, is actually...

Her real-life classmate, Han Do-yun! As if that wasn’t enough, Emma, a noblewoman obsessed with Noel, launches relentless attacks on Summer, and Duke Charlotte schemes to use Summer to dethrone Noel as the hero.

Caught in a whirlwind of chaos spanning both worlds, all Summer wants is to grow her crops in peace!
