A Duet Part 1    

Cain and Riku made their way back to Cain's room, expecting to share one last moment with Leo.

However, when they entered, the room felt emptier than ever. Leo was already gone, leaving behind only a single sheet of paper on Cain's bed.

It was just a goodbye letter.

"We're too late. We didn't even get the chance to say goodbye," Riku said, disappointment etched across his face.

Cain stared at the letter, feeling a pang of regret. With a heavy heart, he crumpled the letter and tossed it into the trash bin.

"Hey, C.C.," Riku said, couldn't believe that he had just threw Leo's letter to the bin.

"It's okay. He'll return," Cain replied, casually packing his bag. "This isn't the end of the line. Once we become idols, I'm sure he will catch up to us eventually."
