So, I was originally going to rate this higher because the premise is cute, the characters are so earnest with their feelings and emotions, and I looked forward to how it would progress. BUT if this is heading towards some step-sibling nonsense. DO NOT WANT!

Now, I already have volume two, so let's see where this goes. Hopefully, I'm jumping to conclusions, but too many mangas like to play and giggle around with quasi-incestuous relationships. >.>
