The uke was also kind of dense. The seme was an asshole. Both of them were dumb and slow minded in a way.
*wasn't an asshole. (Sorry out of habit)

^sounds like this couple ^^
YES IT'S THIS ONE! Thank you sm!!!
no problem!!! have a nice day/evening :DD
This bl <Manga> had multiple stories in it. One of it was when the couple already acted like a couple before they even dated so everyone including their parents thought they were dating. As somewhere near the end of the story when the couple officially dated, they told their parents about it who were already discussing about future plans for them and they were all shocked like "WEREN'T YOU GUYS DATING ALREADY??" or something like that. The seme was the tall, quiet type and the uke was the bubbly and cutesy type. I recall them having nicknames for eachother I think. Idk I've read it last year so maybe my memory is a little fuzzy. I also remember that it was just fluffy and didn't have much drama. (Oh, pls just click the follow button if you want notifications for a comment in case you'd like to know the title as well.)
