The way to avoid bad fate is to be with someone who has the opposite fortune as you. ......
One day, a university student Fukumoto is predicted by a fortune teller that he will have very bad luck for a year from tomorrow.
As the date changes, Fukumoto finds himself in one trouble after another as if it were a lie, and he is convinced that his classmate Yukimura, who saved his life in a pinch at the right time, is his savior.
He tries to force his way into a party where Yukimura is present, and somehow manages to get close to him.
He thinks Yukimura is good-looking and uncool, but in fact he is easy to talk to and a nice guy, and Fukumoto ends up getting drunk and stoned.
When he wakes up, Yukimura takes him into his arms and kisses him. ......?
