People trace art everywhere bro. Look at the old Japanese manga same art everywhere. The concept the plot the story was very unique. They could give the artist some sort of penalty or demand compensation but it's no reason to force them to cancel the story at this stage! It's no brainer that the story got so popular and was getting so much attention that's why some lowlifes was just jealous. Also I think the writer also lost the will to continue after they made this such a big deal. The income is very low comparing to the income to persue legal solutions. Sadly it's the reality of most artists in Korea. Minor issues that could be solved by amicable discussion escalate to cancellations because of internet hate!
People trace art everywhere, yes—but tracing art and using traced art to gain money isn't something little, the art that was traced—the artist whose art got traced will gain nothing. Im guessing you aren't an artist by the way you talk so little of people getting their art traced, extremely weird. No matter how high or low the income they get from the manhwa they released, they still released it and claimed it as their own art and they got the consequences from it.
Jealousy is NOT the reason, the reason was that the artist traced someone else's art, got caught and got their consequences of doing so. Please don't be stupid and go fucking educate yourself about the issue, you are filled with so much hatred for people who called him out yet with love for the artist who clearly knew what he was doing and caught the consequences of his actions.

I curse whoever decided to go after sensei at this point of the story! Fuck u and may you rot in hell! Wtf do you mean plagiarism I couldn't find any manhwa resembling this anywhere! An artist now cannot use reference material now!
