Major spoilers, but I put in everything I remember. Pretty sure it is all one book, but might have gotten confused and remembered two stories together. Happens sometimes because I read so many so close together. If this happens, I'd like to apologize before hand.

Genre- romance, one-shot (?)
This girls dying father had her marry this guy (they knew each other and he was either her father's employee, he was the owner of another business, or a business partner, I think the last) and l the dad's last wish was that they would be married for a specified amount of time. During the marriage she believed that he didn't love her because he never touched her or have any obvious indications, so she left and he went after her. They get stuck in a blizzard and when he refuses to leave she says she will, and he rescued her from freezing to death. He warms her up and she finds out later that something ha adorned to her father's company. I don't remember what exactly, but something along the lines of her planning to pay him back for something and something to do with a house she loved (I think the name had something to do with poker or gambling). She finds out that something happened before the marriage and that he married her so that she cold have a normal life and a little later that he loved her the entire time.

I'd say Wakasugita Hakushaku Fujin
