Замуж на неделю

Everything in my life was going perfectly! That is, until the moment I ended up in another world. And it would be fine if I had landed there by chance, but no — I found myself in the place of an aristocrat on the verge of divorce. My predecessor would give anything to save this marriage, while I would do anything to get rid of the arrogant duke, whose wife I have to pretend to be! But this will only last for a week; I'll manage somehow. If, of course, one of us doesn't end up getting rid of the other during that time... And can anything really change in seven days?...
