@bk3k If you absolutely hate incest them i suggest you keep it dropped, but if you're ever the tad bit curious about their future together then I recommend picking it back,
I've been catching up on the series. This isn't strong on character developement, but the romance is handled rather well.
And this manga is one of those rare moments where they never lewded their characters, despite the incest gimmick. For that reason alone (amd curiosity) I keep following this manga.
Still, this is just my opinion so take my words with a grain of salt. My suggestion is that you speed-read the next ten chaps pr at least five. If ypu're bored to death then drop it.
