In a sense.
In the game, you play as Japanese High School student who enters a "dating contest", and he has 101 (or 151) days to get a girlfriend. When he gets involved in the storylines, they often don't relate to the dating contest, and the endings received also pay little attention to the contest.
There's also the option to create your own content, and I'm doing that right now. However, it's much different from what people would expect.
