Before that, they actually helped Koreans learn Hangul. I was also very anti-Japan as a I grew up under typical Korean parents.
But after reading the actual history, there were some good parts during the colonization. Although, I'm not denying the horrific parts caused by war. But that's just war. It's horrible to begin with. Not to mention what Koreans did in the Vietnam War to the locals.
I think part of the hostility from either of the countries is caused by only seeing part of the reality.
That's certainly not a trend in mainstream webtoons, which are usually the Naver Webtoons. Nearly all (can't think of any one based on something) of them on that platform are original content. Sometimes they get published as novels. Like Noblesse.
I think the particular one you mentioned is based on a webnovel (similar to webtoons but novels).
I definitely see this trend in Japanese mangas though.
Unlike some recent hits made by printed manhwa artists, webtoons were initially an amateur thing. Where as mangas always seemed to have a certain level of professionality in terms of detail and storytelling.
That said, it is interesting how Koreans adapt to these technologies really fast and globalize their culture through a media platform.
It feels really weird when you spot someone reading a webtoon in public in the US because that was just native Koreans who lived in Korea 5 years ago.
