Huh! 80%? What are these numbers? A world where the probability of having sex is visualized, and only I can see it! Hospital version: What's the number above your head? HUNTC-340

The girl I liked asked me to confess! But it was a huge joke, and I became a laughingstock. I didn't care anymore… I impulsively jumped. Whether it was good luck or bad, I was rushed to the hospital and survived. From that day on, strange numbers appeared in my field of vision. At first, I thought it was a hallucination? But the number appeared above the heads of the people in my field of vision, and the number varied from person to person. Especially for men, it was almost always 0%… But for women, it changed when chatting or becoming intimate. Could this be…? I decided to take the risk, and… sex happened! This means that number represents a high probability! So, acting based on this number, I can become the king of sex in the hospital!
