A little regular coffee shop is owned by an old lady aged 45 years old called Ai. Ai has to survive from the influence of the environment. With the money that she got from selling coffee, she has to support her eldest daughter who is still in college. 

Because her husband has passed away, sometimes Ai keeps on asking to dim the light in her coffee shop. Another suggestion, Ai can sell beers because the profit is high. Choosing beer or coffee is like deciding the fate and principles. Because her small coffee shop is located amongst the karaoke places.
