Continued cause comment was too long:
MANHWA:
Like a Chilling Flame
Good LORD this one is cute, these two are g****** MADE for each other. Interested at the first meeting, catching feelings by the second, eloping by the third 😂 plus she's strong as well, so they be scrapping together. If you read any on this list for the romance alone, it should probably be this one. (Fair warning though, the arts kinda goofy at times)
I Became the Husband of the Cult Leader of the Demonic Sect
Dudes whole life mission is this girl, enough said there lol.
Ending Maker
Bit of a genre departure from the rest of these, but I had to include it because the chemistry and quality of the relationship is unmatched in action adventure stories, they are both the protagonists. Unfortunately it's been on hiatus for a while now and I'm starting to worry it won't come back 😭
There's many more I can't recall, as I lost most of my bookmarks when bato shut down and I'm still recovering 😭 but if none of these appeal or you just want more, lmk what kinda genres you like and I'm sure more will come to mind.
