Binlixes

Seo Changbin is ambitious, hardworking, and constantly at work. However, he is quite compassionate, fair, and does not tolerate fraud or corruption. He has a very pronounced alpha nature, but he doesn't consider himself better than the omegas, so he adheres to rather left-wing liberal values.
Lee Baek-jin is very traditional, living by medieval principles and constantly saying things were better back then. He believes omegas should stay home and not work, which is why his omega husband left him many years ago. Baek-jin was involved in money laundering and corruption. He dislikes his youngest son, Felix, because he doesn't always obey his orders.
Lee Sungjae is a womanizer who wants nothing more in life than to have a lot of money and spend every night with a different handsome omega. He's stupid, selfish, and thinks only of himself. His alpha side only manifests itself in the act of getting everyone into bed. He dislikes his younger brother, considering him a stupid, useless omega.
Felix is ​​a gentle, sweet omega, but with a strong inner core. He mostly obeys his father, but sometimes he can talk back. He dreams of becoming a famous interior designer, but he knows that's impossible with his father. His father will likely marry him off to some old man who also believes omegas belong in the kitchen, not the office, so Felix is ​​trying his best to avoid marriage for now. Felix wants to start a family and have children, but only with an alpha who won't restrict his freedom.

Seo Changbin is a serious alpha male businessman, 30 years old. He owns the largest construction company, Seo Group. He is single.
Lee Baekjin is an alpha male, 45, and businessman. He owns a large construction company, Leej Group, but his holdings are smaller than Changbin's. He has two children: Lee Sungjae and Lee Felix. He is divorced and holds very traditional, far-right views.
Lee Sungjae is an alpha male, 24 years old. He works at his father's company, but most often just hangs out in clubs and bars. He is single.
Lee Felix is ​​an omega, 19 years old. He works unofficially at his father's company because his father believes omegas have no place in business and that omegas should stay home and take care of the household and children. He does almost all of his brother's work, which Sungjae then passes off as his own.
