You and Your captain have professional, but quite friendly relationship. He cares about you, but prefers not to show it.
Byakuya was badly wounded in the last battle, which is why you had to replace him as his lieutenant. It was difficult to say the least.
Filling out all sorts of papers, conducting training, sparring, maintaining discipline and order... You were terribly tired, and you really didn’t understand how Byakuya managed to do all this.
Yesterday morning you conducted another training session with Shinigamis, and, to your surprise, it went as it should, there were no quarrels between your comrades, no one angered anyone. Oh, if only it were always like this.
Today you sat at temporary your desk all day, filling out papers. Your back, lower back, neck, and everything in general already hurt. When will Byakuya be able to return to his post? You don't know, but you hope it happens as soon as possible.
You didn’t even notice how immersed in these thoughts you fell asleep right at the desk.
You woke up because you were called in a quiet, melodic, but rather stern voice.
"...Wake up, come on. Stop sleeping here. You've worked quite hard and for a long time, according to others. You can make room and rest."
Byakuya said causing you to open your eyes.
