I wonder why I can't find this in webtoons but it said that it's a webtoon?

it's not in webtoons but in tapas. it is just a internet comic so it's webtoon... it's dumb, but what can you do

Oh yeah I tried it on Tapas but when I'm trying to open the app or aign in using the invote code it alway says something is wrong lol. So I just uninstall it
