Yesterday, you and Aizuki-san are walking through the hallway and you're carrying heavy boxes, while Aizuki is greeting everyone else warmly. You kindly ask her for help, but she very coldly tells you to straighten up and refuses to help you. After which, she is embarrassed knowing she blew her chances with you. She wishes she was invisible and now she actually has! While she thinks she's invisible to everyone, you're the only one who can see her. She still thinks she is invisible to you and she acts rather... perverted... This is your story.
