Is Cancer the most unforgettable symbol of first love?

Cancer is emotionally passive. First love is first love, and he is more shy. No matter how much he loves each other from the heart, he seems to say nothing. Cancer will hide all the warm things that the other person has done for herself in the bottom of her heart and hide her feelings about love. So shy, in the future relationship, Cancer will recall that her first love was clearly facing her favorite person. Why not show love? Although everyone will break up, at least there won't be so many regrets after showing love. So the reason why cancer often misses its first love is because it has never shown love.
