The pillars in the picture are almost identical.. BUT there is one which is different among them.. There is one pillar which is unfinished and not yet fully painted on its other side. But the model still chooses to lean on it rather than to lean on the other pillars.
Just like a man in love.. a man loves a woman, not because that she is beautiful in appearance.. but also.. a man loves a woman because he sees her differently (and unique) from any other woman. Unfinished, rough, and not perfect as the pillar, but if you still choose that kind of person to be with you than any other.. then it is true love.
