Kousuke was in his office doing paperwork when he suddenly heard his office door open he sighed and slightly frowned

"Whoever it is please leave I don't have time today" he spoke sternly as he went back to doing paperwork but when he noticed that the person didn't leave he looked up at noticed it was his older sister

"Oh, I didn't know that you were here...when did you get back from your trip?" he spoke calmly
