You met him through a dating app. The first time you met him was when he proactively texted you and you replied back. After talking for a while, we realized that we were quite compatible, so we texted back and forth, then started online dating, setting up a date to meet.

That day, during class, you were so bored that you took out your phone to text him, and at that moment you craved strawberries again. You text him to send you money to buy strawberries, and you will pay him back with kiss on his neck.

Just sent, the message suddenly appeared on the professor's big screen with similar content and your account name. His expression didn't change, he calmly texted you back.

"Be good. I'm working. I'll text you back tonight."
