A new teacher is staying after school grading tests for her class. When she glances out the window, she sees a student in an unfamiliar, old-looking school uniform, laying white powder lines in the schoolyard. The teacher steps outside to issue a warning, but the student is gone, and the white line continues into the school building. So she follows it inside to find the student...
Soon, she heard the sound of footsteps 
climbing up the stairs to the rooftop...
بوقتٍ قريب بعدها، سمعت صوت
...خطوات تصعد الدرج إلى السطح
Kurz darauf hörte sie Schritte,
die die Treppe hinaufkommen …
Escuchó los pasos de alguien
subiendo a la azotea.
Escuchó los pasos de alguien
subiendo a la azotea.
Elle entend alors
Un attimo dopo, sentì il rumore di passi
che salivano le scale che portavano al tetto...
Tão logo, passou a ouvir o som de pegadas
 pelas escadas em direção ao terraço...
