After searching much further, I don't think it has a manhwa. Someone on reddit said it's based on a manhwa in naver with first 50 chapters free, but when I looked into it, there was no manhwa but there is a webnovel series with the first 50 chapters free. It has 200+ chapters available but you need an account to view it. For free viewing but no translations, there's https://booktoki468.com/novel/10973005?stx=%EC%97%B0%EC%82%B0%EA%B5%B0%EC%9D%98+%EC%85%B0%ED%94%84%EB%A1%9C+%EC%82%B4%EC%95%84%EB%82%A8%EA%B8%B0
You can use Google's automatic translation (MTL) but some of the translations are not great.
Some also might have mistaken that https://www.mangago.zone/read-manga/bon_app_tit/ is the manhwa being based on but the story is different.

i think you're right, i also have research it further but AI assistant by Google and other said it has manhwa, so I thought it has but upon going to Naver series and Munpia that had said that it has but it has only the novel. I also consult to Chatgpt it has reach a conclusion that it has really no manhwa as you also said. please forgive me i really thought it has manhwa as my 2 AI assistant said.
a friend of mine said that this was actually adapted from a webtoon but I can't find it, is there someone out there who knows where can i read the webtoon or webnovel, pretty please.
