[HUNTC-558] Huh!? 80％？ What is this number? A world where the probability of being is visible and only I can see it! Home drinking edition

The club I belong to has a drinking party every month. Usually, at the end, I end up drinking at someone's house, and drunk people get angry with each other. However, as a shady and virgin, I didn't have such a chance at all, and I was in agony as usual tonight, but I was forced to drink a strange drink, and when I fainted, I could see the numbers and percentages above everyone's heads... If I act with that number in mind, I have a chance to have sex! This is amazing! You can tell the estrus state of a girl as if you were in your hand! Moreover, it's the most exciting thing to see an unexpected girl super! Say goodbye to characters with a lot of people! Today, I'm the protagonist behind the scenes!
