Despite not being Yu Yeong's real brother, the young master's father had raised Jun as his own son. He never made any distinctions between them, always showering both with the same love and attention. The servants, though, knew best about their master's feelings.
In truth, Commander Yu felt like he had gained a daughter and a son, instead of two sons.
Mainly due to Yu Yeong's delicate and frail appearance, as well as his beautiful face, he was sometimes treated like a sweet daughter. As if Commander Yu felt the need to demonstrate this through actions, he occasionally dressed Yu Yeong in girls' dresses.
After getting drunk while thinking about his departed wife, the distressed Commander Yu always wanted to see little Yu Yeong dressed in beautiful pastel clothes.
Meanwhile, the same Commander Yu had taken Jun under his wing and taught the young boy the art of sword wielding.
