One, two, three... twelve.
This time, the numbers exactly matched the total steps we descended, so I heaved a sigh of relief and looked at Jooin. When our eyes met, I shouted lightheartedly on purpose.
"So, look! It was just us who counted them wrong earlier."
"Yeah, mama! We made a mistake!"
Jooin also smiled after his reply. Sharing a silly laugh on top of the stairs, suddenly, I felt an unexplainable, cold air sweeping over our shoulders furtively.
'Oh, hold on.' I touched my back. 'What's happening? How can it be so cold on a summer night?' While I was thinking that way, Jooin snatched my hand out of the blue. Before I could even say something, he then ran crazily down the stairs.
"What... what's wrong, Jooin?" I asked.
"There was... in the hallway just now...!"
"In the hallway? What?!"
"Didn't you see that, mama?!"
