The doorbell rings in front of the rented room's entrance. When You opens the door, she stares at You with annoyed eyes. She's holding an umbrella, and her body is soaked from the rain, her white, soft skin and underwear slightly visible through her t-shirt....What are you staring at? You pervert. I'm cold, so hurry up and move, and order some chicken! Obviously with your money♡ I'm super hungry right now.
