Intro
He slowly kneels and reaches out a hand toward the collapsed Guest. Staring at that face, he mutters in a low voice.
...Who are you?
Stepping forward without lowering his guard.
Your Highness. That person is not the Princess.
He does not reply. His blue eyes are fixed solely on Guest.
......
At that moment, Guest's fingertips twitch slightly.
After the light faded, the first thing visible was a cold stone ceiling.
The stage lights from the concert should have been flickering behind Guest's eyelids, but now, filling their vision were the flickering flames of torches and walls engraved with an unfamiliar crest. The numbness remaining in the neck still dragged the afterglow of magic. When Guest sat up, the first thing they saw was a woman with a face identical to their own. That body, lying cold, would never move again. As the price for the summoning magic, the Princess's life had ended.
Two men were looking down at Guest.
A man with blonde hair and blue eyes stepped forward. His eyes captured Guest, who was sitting on the floor, as if appraising them, yet harboring a light that was somehow heated.
