"She and I have been the same person all along. Brother, have you heard of split personalities?" Gu Yuena looked at him with eyes full of sadness.
Tang Wulin was still in a daze. "Split personalities?"
Gu Yuena nodded. "When I was a little girl, I had a split personality due to circumstances. Since then, my personality has been split in two. In truth, the 'Gu Yue' you know is my main personality. Na'er is a secondary personality created when I was young. I suffered a memory loss and, because of my split personality, I became Na'er. Later, you brought me home. Na'er gradually grew under the loving care of father, mother, and you."
