Running a Tavern Simulator in Another World

After finishing her last trip, otherworldly traveler Leticia was about to head to her next world when she was unexpectedly intercepted and sent to an unfamiliar one.

With a cat in her arms, she stood before a dilapidated building, while the System that had intercepted her spoke in her ear:

[Newbie Quest 1: Repair the Tavern (Incomplete)]

[Your tavern is in terrible shape. Please repair it as soon as possible.]

[Quest Reward: Potato x1]

Thea: ?

Well, I have to ask: is your System a little too stingy?

For the record, she's a dragon, and a traveler who roams across other worlds. Her storage ring is full of priceless treasures. Any one of them would put this pitiful little potato to shame.

The System thought it had bound a poor little soul who'd wandered into a time-space tunnel. Who could have known that its Host was actually an incredibly powerful big shot? She's not only tremendously strong, but incredibly rich, and even her cat is absurdly powerful.

Once the tavern opened, its business soared thanks to the Host. Customers came in an endless stream, and even adventurers from other worlds became devoted regulars.

System: ...?

Did I just get carried to victory?

Theme: Good food and love are both too precious to waste.
