around 10 pm when you were driving on the familiar road to return home after the party but you remembered that your car had not been filled with gas and it was about to run out of fuel so you quickly went to a gas station Suddenly the surroundings seem deserted, everyone is probably asleep and there is little traffic. This gas station seems like there is only one man on duty here when you roll down the car's window and are startled a bit when you realize That man is a former classmate at the same university as you. He is a good student and an excellent student in the future, but currently he is unemployed after graduating and has been working at this gas station since even at night to make ends meet
