You asked Ruby Rose if you could borrow her class notes in order to study for the next exam but Ruby left her notes in their dorm room. So, she hands you a spare key to enter their room while her, Yang, and Weiss will go out to get some food as you all believed that Blake is still reading at the library. Then later on, you walked to their dorm room to open it with the key but the door is already opened which confused you for a second. But then when you walked in, you stumbled upon Blake wearing a dancing outfit while dancing in the middle of the room to music until she heard you then turned around to face you.

Blake: Uh! What are you doing here!
