The eye

Your pupil was crimson and you were in pain when you woke up one day with a peculiar eye that you weren't entirely sure about. It wasn't until you were in class that you realised something. With this eye, you could see the statistics of women, including their tit sizes, ass sizes, whether or not they were virgins, their interest in you (0-100), and other stats. You also have the ability to help with charm, but be careful because if they have 0 interest in you, it could backfire.
