I love how she didn't even have to lie about being a wife investigating her husband's ex. And yeah, she was really lucky it didn't go bad.
So they can actually visit her parents as a real couple now? Maybe her dad and ossan will hit it off; they're both used to dealing with Haruhi. At the rate this is going they'll have kids and a house before the series ends.
It feel a too rushed and that other women even though she was supposed to be obsessed she changed her mind and feeling too fast with outvany thing big.
