@Umbrecola This is what the user I mentioned before said in a comment on Webtoon:

Hi, I'm the artist of this series. After drawing 44 chapters, I quit the company (because of the conflict with company and script writer). Now i draw my own webtoon name "DARISHA", if you miss my art style, welcome to read DARISHA thank you . P/s: plz prepare for plot twists before reading it...
This is what the person claiming to be their assistant said:

The artist doesnt draw this webtoon anymore. She only drew 44 chapters. Now the others artist draw. The following content is bad, I'm glad she quit. Elios is like the supporting character!!!! I hate it! Now she draws DARISHA and I luv it ❤. If you guys wanna read her next series, with good content, just search DARISHA.
And the artist replied:

It's true. I'm the artist. I dont draw this webtoon now (after drawing 44 chapters). Sorry you guys. I'm not strong to fight with them and I have to quit. If you think Im liar, just check my account, I'm drawing others, you can realize my style. All my fans in my country know why I left. Its not simple to say in one comment. But... thanks for your love to all the characters in this series. It's also hard to me to say goodbye.
I realize I misunderstood everything now that I re-read those messages. The person claiming they're not working on it anymore was the artist (I thought the writer and artist were the same).
The writer must be working on it with someone else, since the series was updated after the artist supposedly left. There's no way to check if the art-style changed though, since the chapters are locked.
But I believe it, since Sauluoi0101's Darisha does have the same art-style as Supporting Villainess's Survival Diary:

I really wish someone that knows what happened would tell us though, since the artist said her fans in Vietnam know why she left.
