For starters, I don't really read much comic books unless it really really piques my interest. Most of the comics I've read are superhero comics and Josie & the Pussycats, and that's pretty much just it. 
I know there are a lot of really good comic books out there but I haven't really come across one with a strong romantic subplot (maybe I'm just looking in the wrong places?) that really appealed to me. The romance doesn't have to be the main point, but I'd very much like it if it's at least 'somewhat' integral to the entire narrative. I'd also appreciate it if it featured a female protagonist as well. As in, she's not a deuteragonist, but the actual central character of the comic. The romance can be gxb or gxg, I don't really care so long as the story and art is palatable! Mature content is a okay as well!
And to clarify, I'm looking for comics (paperback or web is fine). Please don't recommend webtoon, manhwa or manga! At this point I've already read a lot from those mediums but I want to branch out my reading list.
