The theme of self - discovery also frequently appears. As the OC gets involved with Mori, they often discover new aspects of themselves.

One common theme is the discovery of feelings. Since Kyoya is usually so calculating and Haruhi is so down - to - earth, it's interesting to see how they come to realize their feelings for each other.
