My friend is a penny lover.

A penny lover is a chubby boy. His first love in life is money. In this life, he has only one wish, that is, he can stay with money for a long time and sit in the pile of money and count it. Look! Now he is "money crazy" again. I saw him drawing money on a piece of paper with a pencil in his hand, and he kept singing his own change song: "money, money, where are you?" Come and report to me ... "I sang that I have two big heads. No matter what happens, as long as it comes to his lips, it will be related to money. At the mention of money, his eyes lit up and his spirit refreshed. Now, let me talk about his obsession with money. Hey, lend me a book. Xu Haibin shouted at the little rich man. "All right, then." Penny said, and threw a book at Fan. After about an hour, the little money addict suddenly remembered something and said to Xu Haibin, "Oh, I'm sorry, Brother Xu, I forgot to tell you something important." "What is it? Tell me quickly! " Xu Haibin asked quickly. Xiao Qian Fan cleared his throat unhurriedly and said slowly, "I forgot to tell you about the borrowing fee." "ah? There is also a borrowing fee? " Xu Haibin suddenly felt soft in his seat as if he had been hit on the head. "Well, for the sake of our classmates, I'll give you a preferential price. Originally two dollars, four dollars for two hours, has been rising. You only charge me 50%. How's it going? Pretty cheap, right? " As a result, Xu Haibin had to obediently pay the borrowing costs. On another occasion, the grandfather of a small money addict agreed with him that if he got an "excellent" in the exam, he would be rewarded with ten dollars. This penny lover is really a money lover. For this ten dollars, he made a determined effort and got a "double excellent" in Chinese. But I don't know if his grandfather always forgets his promise, or if he can't afford it, or if he was joking and coaxing him, but he was taken seriously by a penny fan. Anyway, his boss was unhappy and kept saying that his grandfather owed him 20 yuan. After the New Year, he is still chanting. I heard that the interest of 25 yuan has gone up again, and it is 45 yuan. This little money addict knows all about his relatives' accounts. This boy really "denies anyone". Do you want to know who this "nobody knows" penny fan is?
