"Seriously? You're giving me a black card?" Serena asked, raising an eyebrow as she cautiously took the card between her fingers, eyeing it as if it were a poisonous snake. "What on earth do I need this for?"
"It's not just any card; it's a supplementary black card," he explained,"And, believe it or not, it's Grandma's orders."
"Grandma?" Serena's eyes narrowed in suspicion as she studied him. "Why would she—"
"She thinks I've been too stingy with you," Aiden interrupted, "According to her, the fact that you haven't gone shopping even once since we've been together means I must be withholding your funds. So, she decided I needed to rectify that. Hence the card. It's linked directly to my account, so you can spend to your heart's content."
