Su Jin realized Hou Hao could understand what she meant. She made a gesture of making a phone call and said to him without a sound.
"Please lend me your phone."
She had been mute for just a year or so. She didn't know a lot of sign language, so she had to rely on the software on her phone. Now that her phone was spoiled, she could only make gestures.
Hou Hao took out his phone and immediately put it in Su Jin's hand.
"Isn't the phone right? I'm so clever. I know all the gestures you make. Here, this is my phone. Take it and use it."
Su Jin took over the phone and immediately edited the text. Then, she showed it to Hou Hao.
"I need to use the principal's phone. There's evidence to prove my innocence. Please help borrow the principal's phone."
Hou Hao immediately made an 'okay' gesture and said to the principal firmly.
