The Newlyweds:

Lee Sungyeol: Son and heir to the Lee Corporation. His owns the Credit Union branch of the family business. He deals with all business relating to loans, credit, money leading. He is a loanshark. He is fierce like his father, and his only weakness is his lovable Dino mother.  

Kim Myungsoo: An average salary man, and genius accountant with stunning good looks. He moved to the city by himself for work but one day was burdened by news of his father's failed business, and debts. He is a very good son to his Appa and Umma. A well rounded family man. He seems cold to his new wife at first. 

The Family

Lee Family: 

Don Howon/Hoya : He is the Godfather. Don Howan calls himself an entrepreneur, but in the world of business he is feared by all. He holds the big key to the "family" business. Father to Lee Sungyeol and Sungjong, he teach his elder son all the ways in doing business and trust him with one of the Lee's company branch. Things started to get messy when he started meddling in politics.

Jang Dongwoo: He doesn't usually stick his hands in the family business, and usually let his husband handle everything. He has his own fashion store. He is Sungyeol's lovable Dino Umma and his main wish is for Sungyeol to finally seattle down and have a family of his own.  

Lee Sungjong: Sungyeol's sassy diva younger brother ("sister"). He follows Dongwoo in managing the fashion business. Still quite young, and fiery. He is protective of Sungyeol and like to come over to his house to play. He would be the typical bratty/troublesome "sister-in-law". Usually judges Myungsoo with everything. 

Kim Family:

Kim Sunggyu: Former pimp  now leading a normal clean life. He gave up everything after meeting the love of his life, and the two settled in the countryside away from the harsh city. His relationship to his son is very good even though they are not really blood related. He tries hard to run a small farm and market business. He is a gentle soul at heart so he often tries to keep the peace within the family. Mostly between his wife and "daughter-in-law"

Nam Woohyun:In the past he walked the streets of Seoul but after meeting Gyu one night and falling in love he seattled down and lead a clean life. They moved to the countryside and started a family together after adopting Myungsoo. Woohyun is strict to his children, and hope Myungsoo would marry a proper, nice, and capable person who will take care of him and help the family with the farm/groceries business. He often complains that he is the only one who ever does anything around the house thats why his body has turn rough.
