That day, with that girl who was soaking wet...

"Rain... I wish it would stop..."
When I was a student, I was alone at home with a wet, see-through girl... I was in a situation in which I could get laid if I pushed her... and I missed out on eating the set meal.
Several years have passed since then, and even though she has entered the workforce, he still doesn't have a girlfriend. He secretly has feelings for his colleague, Rin Yoshida, but she has a boyfriend. However, one day, on his way home after working overtime, he encounters Rin crying in the rain without an umbrella.
Once again, he is alone with a wet and transparent girl at home... Coincidentally, Rin mutters, "Rain...I wish it wouldn't stop..." just like the girl before.
...This is already fate...I won't make the wrong choice this time!
