My Sister Is the Bride at My Wedding

Summary

On the day of my wedding, my parents suddenly show up at my house with my fiancé, Yoseph Caldwell. They say they've decided the bride is going to change.

"Your sister's terminally ill, and her only wish is to marry Yoseph. You're her younger sister, so be generous and help her out."

Yoseph chimes in calmly, "Don't worry. It's just a ceremony. Once she passes, you and I can still get the marriage certificate."

When I refuse, my parents tie me up. "We'll let you out once the wedding's over."

But not long after they leave, an intruder breaks in and brutally murders me.
