I think I've seen that premise in a couple romcoms before... and in some of the pay-to-read webcomics on here. Not that exact plot, but "Divorcing/Divorced couple who hate eachother work together on a thing, ends up falling in love Forreals!" has been a thing.
It's hard to pick, most of the stories in my head are weird, at least weirder than my current project. There was one project I tried to start years ago that was going to be like a plot with porn, sci-fi fantasy about Your Average Guy Going To College, But He's Not Your Average Guy Because He's Awkward And Quarky! He gets abducted by these plant cyborgs from some planet in another dimension, turns out he's a shape-shifting bird dog thing, and his species used to help keep this one type of tree alive via... certain acts, which produced these plant people who then went out to either distribute seeds of other plants, or become trees themselves. The trees producing a spore-like pollen that fertilized the dirt in the area, as well as flowers and fruits (Separate from the plant people pods.) that fed a lot of animals.
Anyways! Some group of humans found their way there years ago, turned the whole planet into a desert wasteland by killing everything, not understanding how the ecosystem worked. They all died off leaving one scientist, and a single tree they isolated in a greenhouse type of dome. The assumption is he wanted to try fixing everything by bringing back the only dog-thing left, turns out he just wants to study the dog, A.K.A the MC. One of the plant cyborgs also develops a thing for the bird/dog-thing man because they basically have brains similar to humans, and are capable of experiencing emotions.
There's more to the story and lore, but that's the quick gist of it. Very weird premise, just talking about it I can tell how weird it sounds. I wouldn't mind trying to pick it up again someday just because I want to see how people respond to the story as it unfolds, and who would actually read this, it would be a great social experiment.
There's also the story I've brought up on the forum a couple times. The one horror/fantasy/road trip story about a god who ends up being turned into a mortal (Kind of.), is imprisoned for a long time in the world it was "mortalized" in, and made out to be a cursed monster along with demi-gods that were imprisoned. (There's like a whole thing about the different gods, how they're created, what the can and can't do, etc.) It gets freed, learns what's been happening to it is bad actually and not normal for this world, so the god gets so pissed off that it becomes a new type of god designed to cause plague/disease and consumes souls. Although it can, and will if it feels like it, consume everything. Ambition is sparked within it brought on by pure anger, it sets off the devour the god that created it, which has no name but is later called "The Roots" as it resembles tree roots.
Long story short the god learns to chill out on it's journey, ends up being devours by The Roots, and is spat back out later as a new god.
It's also a sort of mini "love story" because the god is accompanied by a half god that used to be it's friend, betrays it, then is willingly enslaved out of guilt to make up for what he did. Later on he is no longer a slave, but ends up staying as a demi or follower of this god, because he becomes totally enamored by it as it grows emotionally and becomes less of a creature of horror. The guy has weird taste.
Like the previous story this one also has a lot more too it... like, I can make a novel about all the details going into the lore, but that's the gist of it. I actually would really like to pick this one up, it's been developing in my head since I was in high school, and is kind of my "baby project". The only issue is it's super long, and has a shit-ton of lore details that I would want to make a whole separate book for, so the project is massive. It'll take a lot, I'll have to figure out if I want to dedicate basically the rest of my life to it give how long my current comic is taking.
