To guys saying it is wierd for MC loving Flora after realisation that it was her 9 years ago...
Did you forget his monologue from ther first pages? He loved her before realising it was her.
And about age... Stereotypically Adventurers start their job when they are 12-13. Let's give MC a bit more so he should be 16 when they met... I don't remember Flora age but I assume age gap is something about 5-7 years which isn't so bad as everyone says... And as long as she is legal... Who cares?
