I'm starting to get real sick of this incestbaiting. Third or fourth series now where this kind of thing has happened. I like most of those series anyway, but it's frustrating when I'm specifically following a tag for that tag's content, but nearly everything in it is either smut (which has its place, but I want romance dammit) or an unrequited relationship used just as background setup for one half of the actual main couple.
That whining aside, though, this seems like a solid enough start. I'm also kinda tired of Class S-derived stuff, but eh, not enough to dismiss this just for that.
