While the lady, whose name I forgot already, may just be giving him grief because of her own issues she isn't entirely wrong either. (actually shit, these characters are so forgettable I don't remember ANY of their names)
It seems to me their system connects people who are compatible enough to easily fall for one another. Your first love is always special and it always feels like it's meant to last forever, but it rarely does. (Usually just an anime thing) I feel like this is going to take the boring route and continue that fairy tale bullshit, but it's clear he's also falling for the girl he was set up with too.
