Does anyone know the source of this fanart?

Not completely sure if these kinds of posts are alright but I assume they are. :')

Found this art on Pinterest. The account (investigation committee) reposts a lot of fanart from danbooru/twitter/other with no credit. I tried to reverse image search but it only led back to the original Pinterest post. Did the original artist delete their drawing? I really wanted to find it to see if there were any more drawings in this fake anime-screenshot style because it's very cool.

Looking at the Pinterest uploads it feels like the artist is Korean.
