Twin Rebirth: Sister's Revenge

I married the poorest rough guy in the village, but my sister married a comatose young master and became an enviable young madam. However, less than a year after her marriage, my sister was unwilling to live as a widow. To remarry, she plotted to kill the comatose man, which also implicated me. When I opened my eyes again, my sister had already chosen the poor rough guy, and I knew she had also been reborn.
