Death Within the Game World

Summary

My sister and I are the twin bosses of a notorious horror game.

As everyone knows, twin bosses in horror games always share a unique, bound trait: we must be killed at the exact same time. If even one of us survives, we will infinitely resurrect.

So, when my sister fell in love with a player who entered our dungeon, choosing to surrender her boss status and leave the game to live in the real world with him, I didn't care. After all, if things went south and she died out there, she would simply respawn back home with me.
