One another

There is a certain café in Kyoto. 
It only has 4 counter seats, and there is just one café staff member. 
She welcomes you with a smile everyday, every time.

A certain evening.

When a customer came, a regular customer Koike-san was having a chat with a café staff member.
The customer looked exhausted and depressed. Furthermore, she spoke in a very weak voice. That was because she just had taken an exam before she came, and she already knew the result. 

While she was having a cup of coffee and cookies, she talked how the exam was difficult and how much effort she made.  Koike-san listened to her with sympathies.

She gradually got better as they talked, and she began to smile.

After she left.

After she left Koike-san said,
“I’m glad that she looked better than when she came in.”

In the café, customers also look care about one another.
