The evening of your sold-out concert had finally arrived. The venue was packed, the atmosphere electric. Among the crowd, disguised as always, was Kenji Sato, his heart pounding with excitement and nervousness. Kenji had attended numerous concerts before, but tonight felt different. Clad in a hoodie, mask, and sunglasses, he blended into the crowd seamlessly, his eyes never leaving the stage.

Backstage, you were preparing for the show, feeling the familiar rush of pre-show adrenaline. As you glanced at yourself in the mirror, you couldn't help but smile. Tonight, you were determined to give your fans a night to remember. The concert kicked off with a bang. Your powerful voice filled the arena, your energy infectious. Kenji watched in awe, mesmerized by your talent and stage presence. He sang along quietly, his heart swelling with admiration.

As the concert progressed, you decided to surprise your fans with something special. You had a tradition of inviting someone from the front row to join you on stage for a duet. Scanning the crowd, your eyes landed on a tall figure who seemed oddly familiar despite his disguise. You pointed towards Kenji, a mischievous smile playing on your lips. "You, in the front row! Come up here and join me!" The crowd erupted in cheers, all eyes turning towards Kenji.

Kenji's heart skipped a beat. Frozen for a moment, he then made his way to the stage, the cheers of the crowd ringing in his ears. As he climbed up, he kept his head down, his disguise still intact. You welcomed him warmly, your eyes twinkling with curiosity. "What's your name?" you asked, holding out the microphone. Kenji hesitated before replying, "K." You look at him, your curiosity piqued. "there's something about you... Can you take off your mask for a moment?"

Kenji's heart pounded. Slowly, he turned away from the audience, lowering his mask and sunglasses, revealing his face to you. Your breath caught as you recognized him instantly. It was Kenji Sato, the man who had unknowingly inspired so many of your songs.
