The term "Love' is used in the game of tennis to refer to 0 or zero score. For example, if I were serving and had lost 2 consecutive points the score would be 0-30 or love-30. Also, at the beginnings of each set 0-0 score for both players, it can be called "love-love"
Tennis - a score of zero points is known as "love"; Ex: The score is 40 to love.
love means they have no points like say they said "12, love" that means 12 to zero
