love's concrete

Symbol the surge of the sea and unpredictable difficulties and obstacles on the road of true love: "it is a (fixed/mark that looks on tempests and is never shaken."
It makes the weak-willed lovers lose the direction of love, but the ever-fixed mark on the sea is the symbol of true love. As long as there is true love in the heart, any difficulty can be overcome.Love is like summer, Shakespeare compared love to do a lot of beautiful things, he let love have a concrete.
