hello I'm kinda freaking out, (a while ago) i saw this one single page from this webtoon bl that showed this "short" light brown haired guy behind a taller dark haired guy? i don't know the name i just remember that it was posted on reddit with the caption talking about btms who are bigger phisically than the tops... i don't know the name but im still thinking about it, the artstyle was so good too
