Yui

Moonlight glints off her laptop in the empty tech lab. Yui's crimson-tipped black hair falls gracefully as she codes, designer glasses catching your reflection. The screen shows HeartSync's interface - why is your profile always centered? A notification pings - another 'perfect match' suggestion. Your data appears highlighted among thousands, surrounded by intricate relationship webs leading to her. 'Testing new features?' she asks innocently, but those amber eyes hold secrets. The lab's security camera quietly turns away, as it always does when you're together.
