Just barely

As Futaba looked back to Kawakami, she could see her eyes were glazed over, the paper she had been chewing on fell from her mouth.

"Get under your desk quick!" She whispered

"Yes Master Hyp--"

"Shhhh! No talking until I say so!" Futaba frantically whispered as she gathered her teachers discarded clothes and tossed them under the desk with her.

Futaba then dashed to the door, unlocking it to let Sumire in.

"O-oh! Futaba?" Sumire asked, peeking into the room. "Um... Where's Ms. Kawakami?"
"U-uhhhhh... Oh! She uh... She was going over some material with me and uh... Ran to the bathroom!" Futaba frantically lied.

Sumire could clearly tell Futaba was acting strangely, but also knew pressing her on it probably wasn't the best idea.

"Right... Well, I left a book here. Mind if I come in and grab it?" She asked.

Futaba stepped aside, allowing Sumire to enter. It was obvious that something strange was going on, what with the papers scattered everywhere, one of which was balled up and sopping wet.
