I had that same thought!!!! (for different elements, but yep) I did tons of research on what would be allowed on Webtoon, and I wasn't even worried about anything I had planned up until season 2, when it will get wayyy darker.
And then... webtoon switched up and took down ep. 16, halfway through season 1, the very first episode I put up with even a hint of the horror element I want to include... so at this point, why bother sticking with them !! x)
(your art is stunning, btw)
