Gentleman’s Dignityis a story of four men who prove that 40 is the new 30.

Do Jin is a womanizing architect who refuses to admit he is no longer a young man; Tae San is in a very complicated relationship with a woman as cold as an iceberg; Choi Yoon is a shy lawyer still grieving the loss of his wife who passed away seven years ago; and finally, Jong Rok is a presumptuous man married to an older woman just for her money. Do Jin finds love at first sight when he stumbles upon Yi Soo, a high school teacher, on several occasions. The only problem is that Yi Soo has her eye on one of Do Jin’s best friends.
