I dunno what you mean, but I take it that the final result would be that the white walkers break through, scare the bejesus out of everyone, forcing them to put aside their differences and re-unite under Daenerys and her dragons. After the victory, we go back to the status quo: Targaryens on the throne, feudal arrangements that leave most of the houses intact and on their ancestral lands, the peasants back to toiling under their feudal masters.
That's how things always ended during the Middle Ages in Europe. Took a very long time to change, and I dont' see that on the horizon at the moment. I'm only seeing endless medieval bloodshed still.

Oh boy, this one thinks there will be a happy ending.

It's not a happy ending. It's just the kind of ending everyone would be forced to accept to survive against the white walkers.
Probably all the surviving houses (eg Starks) will have lost most of their members by the end, not to mention half their castles will be ruined, lots of peasants will be massacred, etc.
This is actually the kind of ending that made countries like France, Germany and Italy and more out of lots of feudal fiefdoms.
