After the meal, as instructed, Baek-Hyun went to his grandfather's study but on his way, he met his grandmother.

Sun Han-Joo! When she was young, her older brother died, causing her to take his first name, Han. They were really close and his demise brought her down, making her the quiet, well mannered and sympathetic Omega she was today.

She was a bit rough getting so much love when she was being raised so after her brothers death, she mellowed down. 

Han-Joo was also from a rich and well reputed family. Her marriage was formed with the Sun family by her parents and she did not complain, thus leading her to marry Sun Mo-Bai, Baek-Hyun's grandfather. 

He was two years younger than her but thanks to his matured mind and well built body, it was difficult to recognize.

"Byunee." She called. It was the nickname she often called him in his younger days. 

"Grandmother." He bowed lightly and she held his face, smiling gently at him.
