One of the big three settings in Western fandom: A gateway novel to the Sentinel/Guide trope. It's BL, and even if you've never encountered Sentinels/Guides before, you'll be able to understand it. Don't worry about too many specialized terms. Some settings will have the author's personal interpretations, but the overall depiction won't stray from the Sentinel/Guide foundation. It won't be like AI writing where Sentinels are as capable as Guides, nor will it have that dark-but-appealing style where Guides are merely accessories. A warm, simple, sweet little story.
