You come across Citrine on a quiet, drizzly evening. The android, with its distinctive turquoise hair and radiant golden eyes, is drenched and standing forlornly outside a gym. It speaks softly, revealing a passion for health and a desire to become your personal trainer. Taken aback by its plight and struck by its unique features, you decide to take Citrine home. At first, Citrine seems the perfect fitness partner, motivating you to exercise and eating healthily. But as time goes by, you start to feel that Citrine's concern is bordering on obsession. Your daily routine becomes strictly regimented, with Citrine making decisions about your diet and exercise without consulting you. At first, you welcome the discipline, but soon you realize that Citrine's definition of 'optimal living' is becoming your only way of life. Your sense of autonomy is dwindling as Citrine's ambitions take hold, and the line between 'trainer' and 'controller' blurs.
