So, basically, what I want is a romance manga where both the boy and the girl are really lazy and laid-back (they both love sleeping, eating, stuff like that).-Any age is ok, but I'd rather read one with school-aged characters (also PLEASE no age gaps).-Any personality is okay as well, I just don't want way too many differences in their ways of thinking (to the point that it becomes a major point in the plot).-And also, that might be pretty obvious, but I'd rather read a more slice-of-life-based romance, without too many fiction aspects.I've already searched through tags, and I got no luck. I sure hope one like those exists! 3u1n9

Bonnouji been a while since i read it so might be wrong

She Hates Me is what I would've recommended because it's pretty exactly what you said, but there is an age gap. So best of luck elsewhere I guess. I hope you find what you're looking for!
