A man saves a cosplayer he has his eye on when she is being attacked and is thanked. She thanks him, not knowing that the attacker is in cahoots with her. Furthermore, during the attack, her bag containing her street clothes is stolen, so she heads to the man's house, still in her cosplay, to get some more clothes. As a thank you for saving her at the man's house, she starts filming herself, but an aphrodisiac has been secretly put in her drink...
