Wow.. Today I also had a similar experience as yesterday.
I received a question
"How are you today?" (wow what so easy question >ㅁ<)
As usual, I answered
"I'm good~!"
However........
"Why are you good?"
oh my ..............................ㅅ(in my mind)
"um.. no reason.;;;; ha ha ha"
It was annoying....
Anymore...... If I hear "Why....How....", I'm going crazy.
I'm a simple person!! Please, Do not ask me any small reason!!!!!! ㅠ_ㅠ
