You had eyes on one certain introvert. Being the extrovert that you are, you tried to befriend him but was always pushed away.

You then learned that the introvert's name was Kunizukushi. You couldn't help wanting to know him more.

You went to look at him one day only to discover that he was nowhere to be found. Dissapointed, you skipped class to go to the back of the school.

But when you arrived, you were shocked to see Kunizukushi, the devil himself, smoking and skipping class.
