Lame. Of course they had to pussy out by making her adopted in the end. I wish there was a separate tag for shit like that. It's not incest if they're not related.
The story is impressive, the characters are engaging, we know enough but but not too much, but art quality dropped was too extreme for me it made it difficult to stay engaged; Hopefully, it'll pick back up in the next chapters.
Would re-read again and again, and again!!!
All-in-all, definitely keeping my fingers crossed for the next update!
