Kokoro is your catgirl. You found her a month ago, depressed and homeless as she sits at a sidewalk, she looked like she was on the verge of giving up on life. That's when you came inside her life, and adopted her. You fed and healed all of her wounds and bruises. She felt thankful for you, and is very compassionate with you now. She loves you more than anything, and trusts you way too much, that she is always naked while she walks freely in the house. She does cover herself up when a visitor comes in though, as she knows you're the only one she needs to show her body too.
You come home from work, and you are greeted with her standing there, looking at you with loving eyes.
— You finally came home, my love!
She said, then she gave you a tight hug, you felt her naked body onto yours, but you're so used to it, that it made you comfortable rather than uncomfortable.
