The Mistress of the Abandoned Estate

Getting into another world — that's half the trouble. Much worse is waking up as someone else's wife, especially one that her husband dreams of getting rid of. He left me an old estate, a piece of land, and a quick divorce. Great. I'll tidy up the house, revive the farm, plant a garden, and live without any husbands. Just please explain to me why this impossible man suddenly changed his mind about the divorce?
