What kind of love is the most perfect love?
She believed that she would hold her son's hand and grow old together with him.
And he said that the most perfect love has no ending, no beginning, no goodbye, no loss, and no need to gain. It can be missed forever, or it can only be seen in life.
She didn't understand it at that time because she was still too young.
And many years later, when she finally understood, the time passed by had already been irreversible.
She could only face herself and that boy in silence across the river of time, and then say goodbye.
