I've only read seven chapters so grain-of-salt here, but by other people's comments I'm given to understand this ends
somewhat inconclusively with regards to the main love triangle
which honestly puts me off from reading further than where I am now...
I mean, this is full of annoying moments just screaming "WHO WILL SHE PICK! DUH DUH DUH"—and tries to make that the main point of suspense more than half the time...
If the story was actually about the kid and the older sister rather than the kid being just a prop 90% of the time and the sister just a convenient plot device instead of a rationally-acting human being, I might be okay with how the romance is being handled (or at least willing to let it pass), but as it is the whole thing just feels so vapid and pointless.
