Her features are her long, silky black hair and big cat-like eyes. And her tsundere personality. She doesn't talk much, but her actions are super cute. They say that serious girls have sensitive bodies, but this one is really slippery. She's quite flexible. Her sense of balance is also impressive. Come on, come on, come on, let's have a romantic kiss! I'm a perverted old man. Today, Marin, a girl with silky black hair and big cat-like eyes, came to my one-room apartment. She's quiet and just nods silently. I wonder if she's decided to be tsundere. What should I do? Every single one of her reactions is so cute that I fall in love with her.
