The story of Teacher Su and Liang.
A chance connection began at summer's end, then came to an abrupt halt in autumn, though they both thought it was a fated meeting.
A romance blossomed in a study, only to end in heartbreak in the school building, though they both thought their love was unbreakable.
A promise was made that autumn, to be kept in some autumn to come, though neither knew if they would ever get the chance to meet again.
Was this absurd love merely an interlude in their lives, or a love that could never be severed?
