A romp you say?
A Dirty Job, Christopher Moore
https://www.goodreads.com/book/show/33456.A_Dirty_Job
Look, all his books are great. This is probably where I’d start. (But, if you want an irreverent read, you could also try Lamb, the gospel according to biff, christ’s childhood pal.)
“Charlie Asher is a pretty normal guy with a normal life, married to a bright and pretty woman who actually loves him for his normalcy. They're even about to have their first child. Yes, Charlie's doing okay—until people start dropping dead around him, and everywhere he goes a dark presence whispers to him from under the streets. Charlie Asher, it seems, has been recruited for a new position: as Death.
It's a dirty job. But, hey! Somebody's got to do it.”

Boyfriend Material, Alexis Hall

Mmm, great plot? Well, it’s fake dating. Definitely good characters. Funny rom com. Some angst. All ends well for our characters. The audiobook is also rather awesome; narrator is great.

If you like British comedy and sci fi, you could try To Say Nothing of the Dog, by Connie Willis. It’s super British.

Her books can make you feel a lot of things. This one I think was a bit less angst. It’s a delight. Uh, but I can’t promise you won’t feel.
“When too many jumps back to 1940 leave 21st century Oxford history student Ned Henry exhausted, a relaxing trip to Victorian England seems the perfect solution. But complexities like recalcitrant rowboats, missing cats, and love at first sight make Ned's holiday anything but restful - to say nothing of the way hideous pieces of Victorian art can jeopardize the entire course of history.“

You said no emotional journey. Well… think about the Martian, by Andy Weir.

Yeah, yeah. So maybe it’s a bit emo. But it’s definitely a kind of romp. Super POV. It’s also very funny. And alls well that ends well. And the movie was good, too.
“Six days ago, astronaut Mark Watney became one of the first people to walk on Mars.
Now, he’s sure he’ll be the first person to die there.”

Also, someone above said Evanovich already, but I also thought the Stephoe Plum books were hilarious. Like twenty years ago, but I remember feeling like I was going to die laughing through the third or fifth one. So, you know, try the ones PP suggested and if you like, give One for the Money a go. Do not watch the movie.
