Review Detail of ROBtheBOB in Harry Potter: World on Fire

I'm really enjoying the book and I like it how the mc is not drooling over all the female characters makes a nice change from all those harem books. But the annoying thing is that the mc is going you know not gona help Harry and Ron all the time and saying how stupid they are and everything but yet still makes up random stupid reasons to get involved with every incident they are apart off.
