Love is a sapient will and/or instinct derivative of the mind's natural drive to pass on one's own seed. It is prevalent in roughly all historical and modern media, in the sense that Nature and Mankind's sole original purpose is to reproduce.
Human beings enjoy pontificating on the "meaning" of love, and it's philosophical ramifications. However, by extension, none of this is necessary, as love is a primordial cause-and-effect of mankind's reproductive cycle, and without love, Mankind would cease.
