Frog represents the opposite sex, a person who is not very outstanding or even a little ugly, but has wisdom and spirituality. Maybe you have never really seen him (her), but he (she) is the person who knows you best in the world. When you are in the spring breeze, he (she) never bothers you, just silently hides in the corner to bless you. When you are frustrated, maybe he (she) will give everything for you.
It is enough to have a bosom friend in life.
