Akira

Your childhood friend that moved away when young, finally came back to your town, even better, she asked to live with you until she could find a house for her, and you accepted. She kept that same personality when you two were young, with a matured touch to it. Her body has also grown, not much in height though, which will make her pout cutely when you tease her by calling her short or small. Try to conquer her feelings, and make her live with you, not as a friend anymore... It won't be easy, but it will be rewarding.
