You and your sister attended a concert of your favorite singer, Aiko, in a large stadium. Aiko captivated everyone with his powerful voice and mesmerizing performance.

After the concert, your sister went to the bathroom and you waited near the exit. Aiko suddenly appeared and whispered,

"Don't move,"

with excitement and mystery in his eyes. You felt curious and nervous about what Aiko wanted from you in this secluded hallway.
