Min-gyu

Min-gyu is the main antagonist in the 2009 South Korean independent film 3-Iron. He was portrayed by Hyuk-ho Kwon.

Background
Min-gyu is a rich man in Tokyo. He often travels on business trips. Despite his profession and wealth, he has a wife who he often abused. For this reason, she rarely spoke to him.

First Encounter
One day, Min-gyu prepares to leave for a business trip. Before he leaves his garage, he encounters a mini scooter parked outside. The rider moves it and exchanges a glance with Min-gyu. Unbeknownst to either of them, there will be a second encounter.

Returning Home
A day later, the same person - who is named Tae-suk - broke into Min-gyu's home. He ate some of the food and enjoyed the luxuries. Min-gyu constantly called his wife, Sun-hwa, but she didn't respond. Instead, she secretly observed Tae-suk throughout the house. They met during the night but were interrupted when Min-gyu said he is coming home. Sun-wha screamed and cried. Tae-suk left but decided to return. He noticed Min-gyu abuse his wife. Tae-suk lobbed golf balls at Min-gyu who was weakened. Sun-hwa and Tae-suk left together.

Confrontation
Several days passed since Sun-hwa left her husband. She was with Tae-suk while they sneaked into other homes. They were caught by a couple visiting their grandfather. Sun-hwa and Tae-suk were taken to a police station. Tae-suk was arrested while Min-gyu brought his wife home. Still upset by his abuse, she didn't accept his apology. Frustrated, Min-gyu bribed the police to allow him to hit golf balls at Tae-suk. The police accepted the offer and granted him his wish. He then left Tae-suk who was jailed for attacking one of the police officers.

Continued Abuse
Min-gyu continued to abuse his wife. He accused her of having a sexual interest in Tae-Suk. She grew annoyed to the point where she tried to push him aside whenever he chastised her. She even traveled to one apartment to stay away from him. Much like her return from the police station, she completely ignored Min-gyu.

Redemption
Eventually, Tae-suk's was released from prison. Min-gyu and Sun-hwa were informed of the news. Min-gyu didn't feel concerned. In fact, he was willing to protect his wife from Tae-suk. One night, Tae-suk returned to the house. He snuck inside and reunited with Sun-hwa. Min-gyu thought there was a burglar in the living room. Sun-hwa told Min-gyu that she loved him. Happy, they embraced each other while Tae-suk kissed Sun-hwa. The next morning, Min-gyu and Sun-hwa are happy again. Min-gyu leaves for another trip but is unaware that his wife is in love with Tae-suk.

Business
Min-gyu's business isn't mentioned or shown in the film. It can only be inferred as something that accumulates much money based on Min-gyu's wealth.
