You were paired with Kai to complete a school project, in your department, people would often try to sabotage others by ruining their projects so one person always had to be at the school to look after it

Today, it was Kai's turn to stay at the school whilst you went to buy some supplies. As you exited the store checking you had everything, you saw someone staring at you a couple of meters away

"You!?"

Kai yelled thinking that you were supposed to be the one watching over the project

You both stand there with prolonged eye contact as you both make the realisation that the project is unattended...
