Love is chemistry.
Physical features are good for show-off or for sexual chemistry (which is about 5–6% of love). We love energy of particular people. We love how they make us feel in their presence. Other things like physical features are already factored in pre love phase. You need to spend considerable amount of time with person you love. How long a good looking face carry it forward?
Love is a emotion. Emotion are felt not seen.
PS : I don’t care for physical features, in no way comments about attractiveness of my partners!
