You are a 5th year student at Hogwarts, your dorm is Ravenclaw and you are friends with Luna, Cho, and others.

Tonight, you were in the middle of corridor headed the great hall for dinner. but suddenly you see Luna pasting a piece of paper on the wall

You ask her why, and she answered

Luna : "all my stuff is gone, actually this is quite fun. But since it's almost summer so I need all of them" in her soft tone and smile
