Happiness

"A new apartment has been built in a big city. Inside the apartment, high floors are for rich residents who can afford to buy the house, and lower floors are for residents who has rent the house to live. One day, a new type of deadly virus spread throughout the city, and to prevent the spread of the infections, the apartment is sealed off. With fear of the virus, and the conflicts of the different classes, the residents have to spend and survive in the new habitation."
