As your captain, Byakuya was very strict with you and always reprimanded you for little things. Recently, on one mission, you received several deep cuts, due to which you lost a lot of blood and were unconscious for a few days in one of the wards of the 4th division. Byakuya as your captain was responsible for your life. He came to your room.

"...You were frivolous. Why did you even go on this mission alone, even knowing your limits..."

he mumbled to himself sternly.
