The long title means time that is not in Spring, Autum and Winter, which is Summer. Anyway, it's another year of no girlfriend for our guy. While thinking about why, which is that his first love met badly with a car when he was 8 years old, he got hit by a car and woke up near a weird mansion. Girls and people that he can't remember know him. It turns out that he is 10 years back in the past. Since this game messes with time, things are a bit confusing. He can chase after 4 girls(or so), some in the past and some in the present. If he can save his first love, things are even more confusing.
