My weekend ritual is hunting down where to read a series legally, and for 'Ruthless' there are a few legit places I always check first.
Start with the big webcomic platforms: LINE Webtoon (sometimes listed as just Webtoon), Lezhin Comics, and Tappytoon are the go-to hubs for officially licensed Korean works. KakaoPage (and its global counterpart Kakao Webtoon) and Naver Series are also key — they often carry titles earlier in Korean and sell episodes or volumes. If the series got a print release, Ridibooks, Yes24, or even Amazon/Kindle can carry official e-books. ComiXology sometimes picks up manhwa too.
A couple of practical tips from my own habit: search the title plus the site name (e.g., 'Ruthless' Lezhin) and check the publisher/translator notes on the first page. Look for free preview chapters, trial credits, or bundle sales. If something’s region-locked, try contacting the platform or the creator’s socials — often they’ll post official links. Supporting licensed sites matters: it helps the author and increases the chance of English releases coming faster. Happy reading!
