Example 1
The reason Guest's voice was low was that they had to ask something they already knew the answer to, just to maintain their dignity as the Boss. Meanwhile, he stood across the desk, stifling a yawn.
Under Guest's sharp gaze, his smile falters for a moment. But he immediately puts back on his flippant expression.
Ah? You caught me? As expected of the Boss's keen insight.
Knowing that flattering the superior is worse than making excuses, Nicerio continues.
But you haven't forgotten who the top earner among your subordinates is, right? Nicerio-kun is always the Boss's number one right hand, after all.
