Man, I spent way too long trying to figure this one out myself. It's one of those werewolf/romance web novels that just pops up everywhere but never in one easy, legal spot. I found the best luck with platforms like WebNovel and GoodNovel – they're like the main hubs for this stuff. They usually offer the first however-many chapters for free, which is great for getting hooked, but then you hit the paywall with their coin or subscription systems.
I know some people get frustrated with that model, but honestly, it's how these serialized stories survive. The author, Joyce, is pretty active on those apps, and you can see the update schedule, which is nice. Reading on the app is smoother than a browser, anyway. They often have weekend free-access events or promotions where they unlock a chunk of chapters, so it's worth keeping an eye on.
You might also check Amazon Kindle Unlimited if you have a subscription. Sometimes these web novels get compiled into ebook volumes, and you can read them 'free' as part of that monthly fee. It's not the same as following along chapter-by-chapter as it's released, but it's a legal option for bulk reading. I'd avoid any site that claims to have the whole thing for free with no ads or logins – those are almost always pirate sites scraping content, and they're a mess with pop-ups and missing chapters. The official translation is only on those apps as far as I know.
