Sensitive

"Many introverts are also "highly sensitive," which sounds poetic, but is actually a technical term in psychology. If you are a sensitive sort, then you're more apt than the average person to feel pleasantly overwhelmed by Beethoven's "Moonlight Sonata" or a well-tuned phrase or an act of extraordinary kindness. You may be quicker than others to feel sickened by violence and ugliness, and you likely have a very strong conscience."
