QUOTE
The Melancholy of Haruhi Suzumiya follows the high school life of Haruhi Suzumiya and those who are caught up in her antics. While Haruhi is the central character to the plot, the story is told from the point of view of Kyon, one of Haruhi's classmates.
Kyon is a first year in high school who has just recently been able to leave his fantasies of espers, time travelers, and aliens behind him along with middle school. However, when he chooses to speak to one eccentric girl by the name of Haruhi Suzumiya on the first day of high school, he unwittingly sets off a chain of events which drags him into situations entirely different from the real world in which he had convinced himself he was a part of. This turns his world nearly upside down as he is drawn further into a world eerily like the fantasies he had just managed to outgrow, with Haruhi Suzumiya at the center of it all.
Searching for a group that interests her, Haruhi joins and quits every club in school finding only dissatisfaction. Kyon makes a snide remark about her actions and accidentally provides Haruhi the inspiration to create a club of her own. To help start the club, Haruhi forcefully drafts Kyon, who only stays in the club to protect (or try to protect) other helpless victims of Haruhi's "voluntary arrests". However, as the story progresses it is revealed that each of these supposedly "helpless victims" has a specific reason to be there.

Changing in the middle of a class and ending up having the classmates kick all the guys out 
Not talking at all but only when Kyon tries to get her to start a convo.
