Rent

In Sihwa's knowledge of Zhang Zian, he was a cheapskate and a super rational person. He would even clearly calculate the charges of her phone bill with her… So how could he do anything that was meaningless and wasteful? His parents had passed away, but he was still keeping their previous numbers active. It just didn't fit his character!

Zhang Zian didn't know why she was asking such a question, so he nodded. "If you don't pay the bills, the line will be terminated. China Mobile isn't a charity organization, after all."

"So, you've not only been paying the bills, but you've also been charging their mobile phones every day?" Sihwa asked. "Didn't you say that we're commercial consumers of electricity, and it pains you each time you pay the bills?"

Zhang Zian was really speechless. "How much of a cheapskate am I in your eyes?"
