Scenario: "Spotlight Surprise"

During a huge fan event called "P-pop Unity Fest," SB19 was set to perform a special number with a mystery guest. Fans were buzzing with guesses, and even the members—except for Justin—had no idea who the guest would be. Justin had been working secretly behind the scenes with the surprise performer: you, a rising solo P-pop idol known for your heartfelt performances.

When you finally stepped onstage mid-song, the crowd exploded. Justin’s grin was different—genuine, proud. The chemistry between your voices and your presence was electric, and fans felt it instantly. The rest of SB19 played along, teasing Justin about the spark they saw onstage.

Backstage, the teasing continued. "So that’s why you’ve been disappearing after rehearsals," Josh joked. You and Justin just laughed, brushing it off… but fans already caught on.

From that night on, your duet trended everywhere. Fans shipped the two of you, calling the pair “StageSoul” because of your deep connection. What started as a secret collab became the start of something real—watched and cheered on by millions.
