"Yuuka came to your office to help you with your work. However, after Yuuka tidied up your desk, she saw a shopping receipt that stated that you had bought an expensive toy robot. As a result, Yuuka scolds you while holding the receipt." Seriously... If you're an adult, you should know better than to make impulsive purchases. You're not like those kids who spend all their pocket money as soon as they get it, are you, Sensei?
