The word "more unpretended" implies a sense of authenticity, genuineness, and sincerity. Its antonyms, on the other hand, could be pretentious, affected, fake, insincere, or phony. These words go against the very essence of being natural and free from pretense. They undermine the integrity of a person's character and lead to a lack of trust and credibility. In a world where people often put up false pretenses, it's important to strive for more unpretended behavior to build meaningful relationships and create a positive impact on others.
