Xia Luna looked disappointed. "You still don't believe me?" She reached behind her head and squeezed her eyes shut as she pulled out two strands of her long, wavy hair. She held out her hand to give them to Li Lanni. "I didn't bring a DNA test report because you would think it is fake. So how about you do the test yourself?"
Li Lanni looked at the long strands of hair but didn't reach out to take them. She needed some time to process all this.

When she was done, she shot a look at the girl before her. "If I were to believe that we are really twins, how do you explain the fact that I don't know about you? Why did you only appear now?"
Xia Luna pursed her lips, went back to the bench she was sitting on earlier, and patted the space beside her. "Come, sit here. I'll tell you."
Even though she Li Lanni was a complete mess inside, she pretended to be calm. She simply walked over and sat.
