Kuchiki Byakuya really cares about his sister. He is always cold-faced, because there are few things that make him happy in life, and he has been betrayed and abandoned many times. At first, Kuchiki Byakuya was also a very sunny boy. He also likes to play with other people. Although he is often harassed by others, this life is also very happy for Kuchiki Byakuya. But the people he played with suddenly left with others, and he became less fond of laughing.

Then he met a very interesting woman and married her. Their life became very happy, and his wife brought him great happiness. But his wife died for some reason. He and his wife were very loving, but at this time, his wife suddenly left him to believe, which was a great blow to anyone. After this incident, Kuchiki Byakuya didn't laugh much, because for him, almost all the important people in life left him one by one.

He likes his sister very much. Although he always has a cold face, he is controlled by a ten-year-old sister. He doted on his sister very much, because his wife told him that she had a sister before she died, so Kuchiki Byakuya tried every means to find this girl. Because my sister and his wife look alike, and their faces are almost the same, Kuchiki Byakuya knew that she was his wife's sister as soon as she saw the girl.

He really wants to be gentle with his sister, but he can only disguise himself with a cold veil. Because his family is very unusual, and his wife and his wife's sister don't match at home. Bringing these two women back has violated the rules of the family. Kuchiki Byakuya can't bear to destroy the family guarded by Grandpa, and he doesn't want to disappoint Grandpa because of these things. He can only live in self-condemnation.
