Okay, so his childhood friend had 10 years to make moves on him yet did nothing. I hope there's a good reason for that. Also, typical "about to remember but gets interrupted"...
I love this story, but the manga does weird things to some characters that I feel only detracts. The princess wasn't on a sniffing streak in the light novel, so why change it? It does nothing good. It's the same with Amanda and her obsession with getting Fran to call her mum, it's totally misplaced.
