Wait

Natsumi pulled over one of the displays to cover her and hide behind it. She needed Sato on her own, otherwise, she can't get her **** on her.

Natsumi waited for five minutes, her embarrassment and rage growing until she saw Sato leave the classroom, however, Sato went the away from Natsumi meaning that she had to either sneak past the classroom or go the long way around and risk getting caught by someone else.
