And though orihime's behaviour around ulquiorra could hint to her liking him, its not likely because right before she was kidnapped she made it obvious that she had extreme feelings for ichigo. Therefore, no one really knows besides the creator himself. ___________________________ A better indicator for Ulquiorra's feelings is his poem "Because of the heart, I lust for everything about you".
