What Is Love??

Tell me what is love??
Love that people said..
Love that make their heart blind
They said “ i love you “, what is it for?
Love sometime can hurt someone, why does it can?
Is this feeling arise at the first sight?
Or this feeling grow because they used to be together?
Tell me what is love?
Is it the feeling or just the symbol
Present the affection, happiness, sadness, and pain
