The "light" on the "other shore" has never been extinguished. During the years of separation, they each carried their memories and concerns for each other. This thought was like a spark that never went out, burning silently for a long time. Until the moment of reunion, the distance across the shore was bridged, the two clusters of sparks met again, and finally the spark across the bank was saved (the writing is not good, please don't spray)
Purpose: Love someone who is in your heart
