Chunhyangjeon

Chunhyang gives Yi Mongryong a ring as a token of her love for him and promises to stay faithful to him and wait for him to come back in the future and take her to Seoul.

The new replacement is Byeon Hakdo, a greedy and selfish person who wastes his time frolicking with gisaengs.

Yi Mongryong wins the first place in a state examination and he becomes a secret royal inspector, or Amhaengeosa, who investigates and prosecutes corrupt government officials as an undercover emissary of the king.

Yi impersonates a beggar to conceal his identity, but despite this, Chunhyang still loves him and asks her mother to take good care of him.

Deeply moved by her faithfulness, Yi orders a servant to show her the ring Chunhyang gave him.

The common people might get vicarious pleasure from the main characters who get over the difference of social standings and punish the greedy lord.
