Knocking several times clearly heard in Mr. K's ear.
Mr. K, who was initially emotional, suddenly subsided at the knocking on the door that sounded fast.
'Gosh! Did Clara hear me? ' panic Mr. K while tapping his forehead when he realized his stupidity.
He forgot that his study is not a soundproof room.
Mr. K exhaled many times, trying to neutralize the roar of his breath which was originally irregular.
After he felt he was back to normal then Mr. K ventured to open the door to his study.
(Sound the door opened)
"Hey honey! What's wrong? Why knock on my door like that?" said Mr. K as natural as possible as if nothing odd had happened.
Clara didn't answer but tried to glance into the room.
For whatever hunch, Clara sensed something terrible was going on.
"What are you hiding? And what was that noise?" Clara asked at last.
