MANHWAs

theres not really a specific way of looking for webtoons, clicking on the tags helps a lot but they don't always tag a webtoon as a webtoon ya know? looking at other people's list of webtoons can help or you can go to websites specifically for manhwas like Lezhin or LINE Webtoon

tell me what genre u want and ill send u some links :')

i dont know if this will help but these are the ones i've read(yaoi/shounen ai):

If u click on a genre at the top of this page, theres a webtoon subcategory you can click

I recommend searching on Lezhin too

im assuming you are talking about webtoons, not manwha. mangago has finally made a webtoon category at the search page. check webtoons and click search.

if however you are talking about traditional, published manwha, you can probably look for it at baka updates.

Thanks everyone!!!!!!
