I Woke Up as a Little White-Haired Catgirl

Xiaonian woke up one day, just before the new school term, and discovered he had gained three older sisters. A month later, Xiaonian woke up again and found that he had become a white-haired, cat-eared little girl and gained a System. And so began Xiaonian's journey to becoming a girl. This isn't an ordinary transformation story. Look forward to what's coming! (◦˙▽˙◦) After becoming a girl, Xiaonian goes by Xiaomeng. Let me repeat: Xiaoke is from a future parallel universe. She came here by transmigrating, not from the future, so please read carefully. And I absolutely won't kill anyone off. Pure comfort and healing, please enjoy!
