The morning light filtered through the glass window, illuminating the sign for "Sunshine Realty." The little dog, Lele, bounced into the office, hopped lightly onto the office chair, and the moment his eyes landed on the computer screen, an anonymous rental email popped up. "New client!" Lele grabbed the keys with his mouth and dashed towards the rental house. But as he pushed the door open, he froze: the room was piled with clutter, the floor was covered with dust, and even the windows were blocked by cardboard boxes. Lele immediately fetched the cleaning supplies. First, he moved the clutter to the storage room, then carefully mopped the floor with a mop, wiped the tables and chairs clean with a cloth, and even cleaned the gaps in the windowsill. After a while of busy work, the room became bright and sparkling clean, with sunlight streaming through the windows and spilling across the floor. Just then, the doorbell rang. Standing at the door was a little kitten carrying luggage. Seeing the completely refreshed room, the kitten's eyes widened in surprise: "It's so beautiful here!" Lele smiled and handed over the lease contract. The kitten signed her name without hesitation. Looking at the freshly signed contract, Lele wagged his tail, considering the next few shops he had to tidy up, and was ready to get back to work.
