It's not as good as the first, but not too bad. A bit of a waste to let it end here, as there's so much to do with this story. The idea with the Demis might not be anything new, yet still serves as a wonderful base to make it a 10+ volumes series.

Vol2 mostly focused on the romance, so that also adds to the wasted potential.
While I found them cute and was a bit excited, after vol1, to see their love blossom, that kind of faded away in one chapter, when a love rival was introduced. Although it was resolved, it made me loose interest and stop rooting for them. I wasn't really rooting for anyone else, but simply wasn't excited for them anymore.

Overall, it's not bad, I just wish the mangaka focused more on the Demis, rather than the romance drama. Maybe the way the love-rival was handled just wasn't my favorite trope.
