This movie, however bearing the My Wife is a Gangster title has little to no relation to the previous movies.
Soon after, they are attacked by professional assassins. They think that they are after Ki-Chul while, as we know from the beginning, they want to kill Aryong who is the daughter of a boss in Hong Kong and is accused of having killed another boss, triggering a gangster war there. They then separate and Aryong and Ki-Chul's car is chased by the assassins but they manage to take refuge in his family. His parents believe that she is his girlfriend and give him a family necklace to give her. The assassins find her again but she overcomes them, especially the woman who really killed the boss. 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.
After that, she leaves Korea despite Ki-Chul's confession, even if she accepts the necklace. In Hong Kong, her father (Ti Lung) dies from his injuries caused by an explosion decided by the other boss. Even though Ki-Chul comes to support her, she leaves to take revenge. She then fights the other boss's gangsters with success and eventually she faces the boss. After cheating, he was going to shoot her when Ki-Chul arrives, distracting him. The boss shoots Ki-Chul first, allowing Aryong to come close to him and to kill him. Ki-Chul is not dead but is going to leave Hong Kong. Aryong, after becoming the new boss, succeeding her father, is advised by her father's right-hand man not to let him leave, as did her father who let her mother leave and then regretted it all his life. 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). Ki-Chul accepts it and they hug on the motorway.
