[1][2][3] Korean gangster Han Ki-Chul is put in charge by his Big Boss of looking after Lim Aryong who comes from Hong Kong.
They expect Lim Aryong to be some big male gangster but she turns out to be a woman and acts very cold toward him and his associates.
Her efforts are ruined by Yeon-Hee who, taking advantage of Aryong's fearsome aura, 'translates' very threatening sentences.
She then goes to meet her mother who is the reason why she chose to hide in Korea, but seeing that she found a new family and is happy, she gives up speaking to her.
She follows the advice, stopping him on his way to the airport with all her gangsters and proposes to Ki-Chul, the right-hand man making the translation (not always a very accurate one, like Yeon-Hee).
