My bad for not reading the tag, it took me a few chapters to understand they were actual siblings and not just step-bros, but it wasn't as weird as I expected. Their interactions are pretty wholesome and they don't really feel like brothers anyway, at least from a reader's point of view. It's not a masterpiece but it is the least creepy incest bl I've ever read and I'm glad there was no rape involved. The artstyle of this author is super pretty too. That's pretty much all there is to say about this.
