Hunting down the person behind a title has become one of my odd little hobbies, so when you asked about 'His Unwanted Wife' and 'The World's Coveted Genius' I dove in right away. After poking around the usual corners where translated web-serials and manhwas hang out, I couldn't find a single, rock-solid, universally agreed-upon author credit for either title in English-language aggregator listings. That’s not unusual — these works often float around under different translated names, get reposted by fan groups, or are shown on portals that highlight translators and uploaders more visibly than the original author. If you’ve spotted either title on a fan site or a serialized platform, the person listed there is sometimes the translator or the uploader rather than the creator of the original script or art.
If you want to chase the original creator, my go-to method is to find the original-language title (Hangul, Simplified/Traditional Chinese, or Japanese), then search the major native platforms: Naver Web Novel/Webtoon, KakaoPage, Munpia, Qidian, JJWXC, or the relevant publisher’s catalogue. Official releases often have an author credit right on the chapter page. Another trick: check the metadata in places that sell physical copies or licensed ebooks — Kobo, Bookwalker, and publisher pages usually list author and illustrator clearly. Fan-translated chapters sometimes include a translator’s note where they name the original author; forum threads on NovelUpdates or Reddit can also point you to the original title and author if someone has already done the legwork.
One final wrinkle I ran into is that some titles share similar English translations, so two different originals can both be called 'The World's Coveted Genius' or something like 'His Unwanted Wife' depending on the translator’s phrasing. That’s why searching by original script is the most reliable path. I love this kind of detective work — following back to the source often leads to discovering an author’s other works you’d never have found otherwise — and if you enjoy it too, it’s oddly rewarding to track down the official page and give proper credit to the creator.
