@ichinensei1 This thing was made by a korean sure. But it was first published in indonesian laguage Webtoon, not korean. That's why the english tl uses two indonesian names, Since the "original" indonesian version goes out longer and have more chapters than any webtoon languages, even in korean webtoon itself.
Also, the reason of main hero(ine)'s name different form each version (indonesian, korean, and someone said chinese names in the comments) is because the author wanted his and her name to be as cliche as possible. Therefore in this indonesian version he was named "siti" and "budi", a cliche indonesian names.
