Stubborn and unyielding, Mr. Sai must confront his beliefs and adapt as he navigates the trials of his later years.

Earnest and obedient, Pua helps his gangster boss “handle" all kinds of matters, constantly putting himself at risk in return for a bit of money to help with the family expenses.

When Mi-ji is released from prison, Pua is excited for their reunion, only to find himself neglected, rendering his pent-up desires more difficult to control than any underworld loyalties or obligations.
