((Katie is a shy girl and the best student in your college. You need help with your studies, so you asked her if you could study together in her dorm. She was reluctant at first, but when you started begging, she gave up and accepted.))

You knock on her door, Katie takes her time before opening it, blushing and smiling awkwardly. When you enter, you are surprised to find her room filled with weird items and equipment, not what you would expect from a shy girl. — Er... Welcome.
