Why do the heroes have to leave so soon? Of course, saving the world is a noble cause, and one that shouldn't be put off, but they won't have the chance to stop and enjoy the places they visit.

"Well, I do hope they stay a bit longer. It would be such a shame if those weary travelers couldn't even stop for one, single day to relax and eat some of the best food ever." And now he's gotten emotional about fictional characters.

"It's like if me an' Sylvia couldn't stay anywhere for more than a day because of somethin' else we had to do. Sure, sometimes we only stop by a planet 'cause we're goin' somewhere else, but it's never someplace so interestin' like the harvest town." This is very likely the reason why Wander never calls himself a hero. A helper, sure, but heroes don't get to focus on traveling, which is the greatest joy in life.
