The young man fell silent too when he heard this.
After a few seconds, he tentatively asked, "Are you suggesting that despite ascending to the heavens, our Little Junior Sister is still so concerned about me that she used her psychic powers or telepathy to give my number to someone else?"
"..."
There was a pause on the other end of the line.
The conversation dipped into silence again, but this time, the person on the other end was at a loss for words.
Eventually, they replied with a wry smile, "Little Six, you really are something. Why don't you dream a little more?"
"Wasn't it your idea?" the young man, ruffling his hair in frustration, retorted. "It wasn't me who brought up Little Junior Sister. What do you mean by 'if it's not a ghost' then?"
There was a brief silence before the voice spoke slowly, "What I meant was, eliminating all the impossibilities, maybe someone just dialed the wrong number."
