Ella and Niki sat on the curb, their hearts heavy with the knowledge that their paths would soon diverge. "Promise me we'll always be friends," Ella said, her voice tinged with sadness. "Always," Niki replied, squeezing her hand tightly.

Lilly and Hazel exchanged excited glances as they shared their plan with Ella. "There's a Kpop concert in Seoul this weekend. Team79 is performing!" Lilly exclaimed. "We thought you might want to come with us," Hazel added with a smile. "I’d love to!" Ella replied, her eyes sparkling with anticipation.

Ella swayed to the beat, her heart pounding with excitement as the band performed her favorite song. As she glanced around, her gaze landed on a familiar face among the group, triggering a cascade of memories. "Could it be...?" she whispered to herself, her mind racing to piece together the fragments.

Lilly and Hazel grinned at Ella, presenting her with the backstage passes. "We thought you'd like to meet them," Hazel said. Ella followed them eagerly, her heart filled with anticipation and hope.

Ella caught sight of Niki, his eyes locking onto hers with a mix of surprise and recognition. "Ella?" he asked hesitantly, stepping forward. "Niki! It's really you!" Ella exclaimed, her voice filled with joy and disbelief.

Ella and Niki sat across from each other, reminiscing about their childhood adventures. "I never forgot you, Ella," Niki confessed, his gaze tender. "I never forgot you either," Ella replied, her heart full, knowing their friendship had withstood the test of time.
