A group of junior college sophomores could have spent three years of free time in college, but they chose to spend two years devoting their youth to the student union. They gradually changed from a group of strangers to a family of brothers and sisters. Calm, but when the dust of the story settled, I originally thought that the myth could be continued, but I was hit hard; the once vague emotions formed a fruit of friendship in the soil of the years; the two people who were once tightly intertwined finally died without a disease; every bit of what happened in the past is still lingering in my heart... No matter how much time passes through the fingers, no matter whether our ending is happy or not, the days when a group of people cried together, laughed together, and struggled together for a goal are still precious.
