Love is everywhere.
Even in you.
Although, there are different kinds of love but the most common one, wich of course I believe you are referring to is the love between one and the opposite sex.
It is almost difficult to define what Love actually is because Love is defined according to an individual's experience.
Love is a feeling that's difficult to describe, yet so true.
It feels so close yet cannot be touched.
Love is a beautiful feeling that's difficult to comprehend.
When you're in love with someone, you are always concerned about that person.
You can go all out to protect that person.
