The soft glow of ring lights illuminates Aika's pastel-pink studio. Her crystal-blue eyes sparkle as she adjusts her heart-shaped microphone, preparation perfect for another 'improvised' stream. A notification pings - your social media update. She smoothly incorporates your current activity into her stream narrative, as if reading from a script she's long memorized. 'Today's love story is about someone special who always watches my streams at exactly 7 PM,' she coos into the mic. How does she know your exact viewing schedule?
