Jongin

Eldest son of Song Gaelin and Lee Soo-hyuk. He is the Lee Estates named heir and currently Director of Operations at Lee Corp.

Nicknamed Kai by his uncle when he was a baby and only called Kai by Consortium members, very close friends and family.

His favourite person in the whole world is still his mother

He is closest to Sehun and Kyungsoo but sometimes their pedantic rule-following ways annoy him

Kai misses his old HM (Namjoon) and can’t really form a connection to the new HM (Taemin)

Is still a cold city guy to everyone else except his family and Consortium members

In the past, Kai fought with his dad a lot but they are very close now and Kai has accepted his position as the future leader of the Golden Quill Consortium.

He is hot-tempered and impulsive

Doesn’t drink. Had a bad spell of drinking when Kyungsoo was in a coma

Sehun once said of Kai that he is like the light. When he smiles at you it's like the sun is shining brighter but when he leaves you, everything feels cold and dark. 

Sehun

Second born of Song Gaelin and Lee Soo-hyuk. The named heir of the Song Estate

When Sehun was born his grandmother, Jung Minah was disappointed because she wanted a girl but now believes that Sehun is the best heir she could have cause he always spends time with her.

Sehun is Director of Research and Development at Oracle – the Song Family business.

Still called nerd by Kai cause he still enjoys tinkering away at inventions

Is physically the strongest cause of the training Song Gaelin made him and Arran do from the time they were kids

Sehun is closest to his mother

Together with Chen and Kyungsoo (the holy trinity), they keep their generation in check

Sehun has been on a healthy eating plan since he was a kid. He hates and loves it at the same time.

He is thought to be broody or sulky. No one can tell

His weakness is that he likes danger, including dangerous women. 

Baekhyun

The third son of Song Gaelin and Lee Soo-hyuk and Arran’s twin

Sport inclined and plays for a German team and is captain of the national team

Married actress Ji Hyeran after they met at his graduation party. They have no children as yet.

He never did get that indoor astroturf he always wanted.

Considered lively and warm. A charmer who still has a lot of female followers.

Because he is always away (more than half the year is spent abroad) he feels left out of the family and Consortium.

Arran

Daughter of Song Gaelin and Lee Soo-hyuk. 

Looks even more like her mother. Known for her beauty. 

Still a daddy’s girl. 

Head of Design at Lee Corp. Loves rehabilitation projects. Old buildings that she can breathe new life into.

Considers it her responsibility to make sure everyone in the Consortium is happy and likes to play matchmaker.

Still wants to marry Kris but has commitment issues

Arran likes to act cute but has a dark side that she tries to control. Working out with Sehun and the Song House Master helps relieve stress.
