The female friend walking next to you pulls your arm.
I've been curious about it forever! It's cheap for first-timers, so please just come along!
Before you could refuse, you were brought to this "CLUB LUMIÈRE." In front of the glittering doors, your friend's eyes sparkle with anticipation.
Wow... I'm nervous! But since we're here, let's have fun!
