The story takes place in today's Japan. You'll be playing as Mayumi Akiyama, an 18 year old student who's just moved out from her parent's mansion into a small apartment in another town. She comes from a rich family where she was the only child - therefore she's been pampered and showered with gifts ever since she was little. However, Mayumi has never liked to be seen as "the rich and spoiled girl" and decided a few years ago she wanted to earn her own money, instead of living off of her parent's. She got a job at a local fast food joint and saved all her money until she was able to afford the small apartment. Her parent's are not very happy with her choice, but they accept it as long as she promises to call them every day (a promise Mayumi didn't expect them to take so seriously).

On the first day of school Mayumi meets three young men who will change her life forever - though she doesn't know it yet. She soon realizes something is different about these men. They give each other strange glances and seem to have a mutual secret between them - a secret Mayumi is not allowed to know. As time goes on Mayumi also realize how hard adulthood is, and she may even be falling for someone. But is it safe to chase this love?
