For Eagle Brothers

Follows the story of the five unique brothers who run the 'Eagle Brewery', a traditional liquor brewery that has been making liquor for three generations, and the eldest sister-in-law who suddenly becomes the head of the household after her husband's sudden death just ten days after her wedding. It is expected to contain a family story with a unique recipe.
Oh Beom Soo is the fourth son of a 'dog-slinger' who grew up with expectations that he would make his family better, and is the pride and hope of the five brothers. He is a perfect handsome man with an elite aura in his character, brains, and speech, to the point that it seems like he inherited all the good genes from his family.
He took first place in the finance section of the civil service examination while attending Seoul National University, worked as an elite civil servant, and even studied abroad in the United States on a full scholarship. After earning his master's and doctoral degrees, he returned home as a professor at a prestigious private university in Seoul, but he actually has a secret that even his family doesn't know.
