"Hey, that dress would look nice on you." Haruka pointed to one of the shops.
A cute evening dress, it was indeed something she would wear. "I don't have any money," Lila admitted. She did not think they would be gone long today, so she did not bring any cash with her. To avoid being tracked by Zane, Lila tried to avoid using her cards and paid with money. Haruka did the same; for large payments, Haruka used a card her parents gave to him.
It may seem stupid to do this. Zane knows they are in New York. But since nobody has attacked them, she can safely assume that he does not know their exact location.
"Then time to use the in-law's card."
Lila laughed. "You do realize that my father tracks all the things bought on the card, right?"
Even though the money on the card is Harukas, the card is still under her parent's name. So anything they buy with it, her parents can see it.
