Returning To The Past, I Married My Sister's Husband

Synopsis

When my sister and I chose our marriage alliances, she rushed to claim the noble were-dragon, and I married the savage werewolf instead. Not long after the wedding, the were-dragon died. My sister lost her support and suffered constant humiliation. The werewolf, however, proved sharp and capable. He built massive wealth through sheer business talent. My sister hated me to the core. During the sacrificial ceremony, she stabbed me to death. When I opened my eyes again, I found myself back on the day we chose our marriage alliances. This time, my sister grabbed the werewolf's hand first. I understood at once that she had also returned to the past. But my sister didn't know that werewolves were violent by nature. They solved problems with their fists.
