Recommend me show with two messed up people who fall in love.

I’ve been searching for a tv show to scratch a recent itch of mine. I have been looking for a show with a romance slowburn over multiple seasons that’s a subplot but the two characters have to be like absolute messes or absolutely messed up to where they only find comfort in each other. They also have to think they can’t be together for some reason. I’ve found to ships similar to this in Daisy and Robbie from Agents of Shield and Frank and Karen in the Punisher but unfortunately both ships are not canon. Please recommend me a canon ship like this! I’m desperate haha!

Edit: I’d prefer shows with a darker tone but I’m open to anything.
