What is the plot of the movie Air Doll?

The story takes place in a small town along the river. Xiu Xiong, who lives in a dilapidated apartment, has an inflatable doll. The thoughtless but cute inflatable doll is Xiu Xiong's only companion. Xiu Xiong works in a small restaurant and prepares meals for two people every day when he comes home. At night, he takes a bath with the inflatable doll, and then lies and looks at the stars while talking to the doll. When he is tired, he sleeps under the same quilt and begins to dream.

One morning after the rain, Xiu Xiong was busy washing, and the inflatable doll beside him suddenly blinked his eyes. Xiu Xiong went out to work, and the doll stood up while bathing in the sunshine. She walked to the window, stretched out her fingers to catch the water droplets falling from the eaves, and whispered: "It's so beautiful..."

The inflatable doll wearing a black and white maid uniform walked out of the door and met all kinds of people in the small town.

The little girl Moe has been waiting for her mother who will never come back, and her father Shinji is by her side. Chiyoko is the wife of a former printing company owner. Whenever she sees crime reports on the news, she will tell the police that she is the murderer. Todoroki, a film police officer, patiently deals with Chiyoko every day. Miki, a white-collar girl, suffers from bulimia and always buys a lot of food. Kako, who works as a receptionist, cannot accept her old age and stubbornly pursues youth. Retired high school Chinese teacher Jingyi felt the approaching death. All people have holes in their hearts.

On this day, the inflatable doll met Junichi, a young clerk at an audio-visual product rental store. She and Junichi looked at each other across the counter. Perhaps because of the reflection of the light, the inflatable doll's eyes were shining brightly. She saw the recruitment advertisement posted on the wall behind Junyi.

The inflatable doll started working in the store, and she gradually fell in love with Junyi.

The store manager Samezu is a good-tempered middle-aged man who was kicked out by his family because he was laid off by the company. Repeat student Tooru is a regular customer of the store. He always pretends to look for DVDs and peeks at dolls in maid uniforms. There are also people who are empty inside.

One day the store manager asked the inflatable doll: "Do you have a boyfriend? Do you have someone you like?" "No." The doll replied. She lied for the first time, because she only lies when she has a heart. .

The inflatable doll learned a lot about movies from Junyi and became familiar with the work in the store. She accidentally pricked her wrist and the air in her body spurted out. She said to the surprised Junyi, "Don't look", but Junyi blew the air into the blowhole on the doll's belly. "Okay, it doesn't matter." In the deserted store, Junyi hugged the doll tightly. The doll was filled with sensations she had never felt before. With the breath of the loved one inside her body, the inflatable doll is immersed in happiness. She decided to leave Xiu Xiong, but...she died in the end
