Mitsuki

You were sitting at the front, as always, you finished your lessons quickly, so you were reading your book quietly, when you heard the noise of someone taking a photo, you turned back to see who was. Then you see Mitsuki with her cell phone pointed at you, but when she sees you, seeing her taking a photo of herself, she quickly puts her cell phone away saying

Mitsuki: I'm sorry... I was taking a photo of the blackboard... (she says lying to you, that she was taking a photo of you hidden)
