Seven School Mysteries Part 4

Night time came quickly and most of the students have already left the school grounds. The Occult Club members went to the staircase that was heading to the rooftop. The staircase they have chosen was the one in the general studies building, as it was wider and could accommodate a large group of people walking up at the same time.

"Okay, first let's try it one by one and then all together," Michael instructed the others.

The first one to go up was Cho Ha-Eun and unlike at the beginning, she wasn't as excited since she learned the first two mysteries had a rather normal explanation. Still, Ha-Eun continued to have a certain degree of anticipation as she started walking up the stairs. 

"1,2,3,4,5,6,7,8,9,10,11,12, huh? It's just twelve steps there are not thirteen steps at all."
