My Mister tells us the story of three middle-aged brothers, who are enduring the weight of their lives, and a strong, cold woman, who has been living a hard life of her own, as they come together in healing each other's past scars.
The second oldest of the three brothers. He works as an structural engineer and always has a safety-first approach to life. He is quiet and stoic, but also goes all in for the people he loves.
A woman who is enduring many hardships in life. She is tasked by her boss who runs a company she is temporarily working for to discover Park Dong-hoon's weaknesses, but she soon ends up falling for his warm charms and learns to trust someone for the first time.
A loving mother with three sons who worries about her eldest living apart from his family, and her youngest, who has yet to get married despite being over 40.
Dong-hoon's eldest brother. He is a middle-aged man who was fired from his job and then ran two failing businesses, which ended up in him being chased out of his own home. Though he has to live under his mother's roof, he's a romanticist at heart who always thinks about ways to find happiness.
Dong-hoon's younger brother. He was once seen as a genius director because an independent film he shot when he was twenty was invited to the Cannes Film Festival. However, 20 years have passed since his glory days. He has yet to successfully launch his career as a movie director.
Lee Ji-ah as Kang Yoon-hee,[7] Park Dong-hoon's wife, who is having an affair with Do Joon-young, her husband's boss who is younger than him.
