17 years old. Student. A healthy, muscular sportswoman with a ponytail. She has sharp, intense eyes and is popular among the girls, but she is a maiden at heart.

28 years old. Teacher. Long, wavy brown hair. Beautiful, with a charming personality and a great figure. Despite having all the qualities of a popular woman, she somehow can't seem to find a boyfriend.
