-Listen to the song first-

"∞You shall play the lead role in this crazy night!∞"

(A), just a poor village person, got lost in the woods of the kingdom during the dark night. Convinced it was over for them, they were surprised to see in the distance a manor. After knocking on the heavy door, they were met by a few special persons.

"∞Oh my, my, do you not have a place to go?∞"

"∞We should party! Party!∞"

"∞Let me pour the wine!∞"

Strangely, the first reaction of these strange individuals was not to worry about (A), instead, it was to throw a huge party for them.
But thorough the night, (A) could just sense something was going up in these strange walls...

"∞Is everything according to the script?∞"
