A rainbow is a special phenomenon.
Love is a special feeling.

A rainbow has different colors.
Love has different feelings.

A rainbow has both light and dark colors.
Love has both positive and negative sides.

A rainbow is only created when the sun and water droplets meet.
Love only comes about when two people meet.

A rainbow doesn't go away as long as the sun and the water drop are still together.
Love does not go away as long as two people still love each other.

Everyone knows a rainbow.
Everyone knows love.

But not everyone sees a special rainbow.
But not everyone can get true love.

A special rainbow only develops when the sun and water droplets are strong enough.
True love only develops when two people love each other strong enough.

A rainbow is like love ...Love is like a rainbow ...
