Anybody else get that 'back of the book' feeling of desperation from the title alone? It screams a specific kind of webnovel heartache. I dug around because a friend was obsessed with the manga adaptation. The original webnovel, if you can find it, is scattered across a few Japanese sites like Kakuyomu or Shousetsuka ni Narou, but it's not officially translated and those sites are a pain to navigate without decent Japanese.
Honestly, your easiest bet is the manga version. Sites like MangaDex often have fan-translated chapters floating around, and I've seen it on some of the bigger aggregators too—though quality varies wildly. The story itself, this intense protector dynamic with a supernatural twist, translates really well to the visual format. The art captures the desperation better than some prose I've read. I ended up just following the manga releases on MangaDex and calling it a day.
