One is to leave her hometown to pursue her youthful ideals, the other is to fulfill her filial duty and marry Chai - the richest young master in the village.

Chai loves Pu passionately and has only one goal in his life: to marry Pu. Because of his love, Chai tries every way to prevent Pu from leaving him. Chai's childish love becomes an obstacle on Pu's path to education.
