Late stage Dangerous Convenience Store is pretty cute. Taming the Tiger is top tier and they are SO LOVELY. Do prepare for angst though, but it's worth it! I'd also recommed Define the Relationship, though it's a bit frustrating getting there hahahaha. And it probably does not fit your description as much, but Shutline is top tier. They don't explicitly say they are in love, but god, you can FEEL it!!!
My perverted stalker is another good one (ignore the name lmaoo) it takes a few chapters for rindo (uke) to fall for amane (seme) since amane is pretty creepy but once they’re together they’re so in love even when they go through really bad things (there’s a lot of conflict and angst lol) theyre always thinking about each other. It’s soo cute and borderline codependent
are there any manhwas that are the same as this story? like couples being in love and all. coz i rarely see manhwas with couples being so in love especially during seggsy scenes
