Since he was not clear on whether or not to keep the dog, Liu Sanlang only bought one bag of dog food. If he decided to keep it, he would buy other pet supplies later. He was quite nervous that the dog would pee or poop in the aerated box, so he kept staring at it. Fortunately, the puppy didn't do anything embarrassing.
Liu Sanlang opened the box and let the puppy out when he got home.
Liu Sanlang was, in fact, a homeowner. His apartment was a small two-bedroom. His parents gave him some money towards the down payment and he was paying the mortgage on his own. He was fortunate that he bought the apartment early, because the real estate market was skyrocketing high at the moment and it most likely would continue to grow. If he hadn't invested in the apartment back then, he probably would never have been able to afford one. The mortgage was high, but it was worth it.
