HUNTC-476 What!? 80%? What's this number? A world where the probability of getting laid is visualized and only I can see it! 4 What's that number above your head?!

What's that number above my head?! I was kicked by a classmate, fell down the stairs, and knocked unconscious. But when I regained consciousness, I saw some numbers and percentages displayed above the heads of everyone I could see! What on earth are those numbers? However, the numbers go up and down whenever I make a move. The change only affects women. Maybe... I tried various things, half-believing, and realized that this might mean I could have sex with them. So I decided to use all my effective strategies to have sex with the girls in my class! Of course, female teachers are also my target! I'll identify the most likely moment and touch their bodies, so there's no way they'll reject me! My school life has begun, and I'm sure I'll win!
