just in case im leaving it here..
"The webtoon is based on a webnovel by White April. It seems that season 1 and season 2 have two different artists/webtoon writers adapting the story.
Season 1: Art/webtoon adaption by Bada.
Season 2: webtoon adaption by Woosaem and art by Yonggo".
the reason why the artist changed still no hv been found yet.
