Grandpa Lee didn't let anyone else take over the CEO position and he himself took it over for the time being and hoped for Choi Hyuk or Lee Aera to prove they are worthy of this position.
Aera was not interested in business so she gave it up for her elder cousin brother Choi Hyuk.
Aera has always been close to their elder cousin brother Choi Hyuk, while Kiaraa was close to their younger cousin brother Lee Gun.
Choi Hyuk had been trying very hard to prove he can run the entire business empire but he kept failing to prove himself and for the last nine months, Lee conglomerate didn't have a permanent CEO.
Song Ji Hun was sure his wife, Kiaraa is still eying this position in spite of the fake act she was putting on.
Aera was the most affected when she heard Kiaraa's words, her sister was not leaving any chance to claim the man she had always been in love with as her own.
Aera was sure Kiaraa was only saying to piss her and she is not truly in love with Song Ji Hun.
