If you're hunting for a legal place to read 'The Heartbreak Diary', I usually start at the major official platforms because that's where creators get paid and translations are safest. For
WEBTOON-style or serialized comics, check out Webtoon (LINE Webtoon), Tapas, Tappytoon, and Lezhin — those are the big ones that often carry English translations. If the work has a print or compiled digital release, you'll often find it on Amazon Kindle, Google Play Books, Apple Books, or BookWalker. I’ve personally bounced between apps depending on sales and which one had the cleanest reader UI at the time.
Another thing I do is look up the publisher or author’s official accounts; they usually link to the authorized stores or reading platforms. Sometimes a comic starts as a web serialization and later gets collected into volumes sold on Kobo or Kindle, so keep an eye out for both serialized and volume releases. For Korean-origin titles there are region-specific services like Kakaopage or Naver Series that may have official English versions through partners; for Japanese-origin works BookWalker and ComiXology are often where the licensed digital editions land. There’s a mix of subscription models (like Webtoon passes) and buy-per-episode or buy-full-volume options, so compare prices.
I also use library apps whenever possible — OverDrive/Libby and Hoopla sometimes carry licensed digital manga/novels, and that’s an awesome legal option if you just want to read without buying. If you prefer audiobooks or novel formats, Scribd and Audible sometimes pick up licensed titles. The core tip I always give friends is: avoid unofficial scanlation sites. They might be faster, but they undercut the creators. If you can’t find it on any of these major platforms, check the publisher’s website or the author’s social feed; they often post official links when new language licenses are released. Personally, I don’t mind paying a little to support the creators, and it makes the reading experience guilt-free — plus many platforms run legit sales so you can snag volumes cheaper.
