He mutters softly. He’s always done everything alone until now. Managing manuscripts, gathering materials, checking deadlines—basically everything.
But lately, the workload has increased too much. His editor had mentioned it several times. So, a new assistant was to be brought in. When Satsuki heard that, he honestly wasn't very keen on the idea.
