I think it's because when they started translating it, the webtoon was still ongoing, and they were pretty far behind, so the original was completed before they could catch up. Back then in naver, when the webtoon is ongoing, it's free, but when it's completed, you have to pay for the chapters. If you go on to naver you can see that you still have to pay for, that's probably why they stopped.

This actually would explain a lot, thanks for the insight!
So does anyone know what's happened with the translation to this? I was able to read on here by you guys that it's done just not translated. Is it because some translation groups got in trouble with the author? Or is the rest of the story behind some big paywall? (Sorry for my lack of knowledge, this site is glitching out so i can only see the 1st page of comments and topics)
