I dug around my usual places and, honestly, the credits for 'Young Boss' can be a little fuzzy depending on which translation or platform you're looking at. What I can say from poking through official chapter pages, publisher listings, and reliable scanlation notes is that the best way to get a definitive creator credit is to check the original release page (Naver, Kakao, Bomtoon, etc.) or the licensed publisher's listing — that's where the author and artist are listed together. Sometimes the writer and the illustrator are the same person, and sometimes they're a duo; it varies by title and edition.
If you're hunting down the names, look at the chapter header or the series info box: authors are usually noted as '글' (writer) and artists as '그림' (artist) in Korean listings. Fan wikis and aggregator sites can help, but they occasionally copy bad data from scanlators. I also like cross-referencing library or bookstore pages for licensed volumes because those almost always list creator credits correctly. Personally, I find the art style in 'Young Boss' evocative of
modern romance-comedy webtoons — so tracking the artist through an image search or an artist's social media can confirm who drew it.
Anyway, if you want a rock-solid name, the official platform page is the gold standard. I always enjoy seeing the creator credits because it leads me to other works by the same team, and with 'Young Boss' the style hooked me immediately — such a slick blend of character expressions and panel pacing that I kept flipping chapters just to study the staging.
