Tokita, a female college student who drank too much at a drinking party on Friday, wakes up on Saturday morning to find a male friend from her club sleeping next to her. Maybe he did it in the heat of the moment... She begins to feel anxious, but her male friend wakes up. When she is unable to confirm whether they had had sex, he becomes overly familiar with her. Tokita, who is weak to pressure, ends up having sex with him while conscious this time. But that wasn't a bad thing... in fact, it was good. From there, they start living together on the weekend. They have sex, eat dinner, and have sex again. They sleep, wake up, have sex again on Sunday, go to the convenience store and have sex. Tokita, who didn't have much experience with men, wakes up to the best weekend sex ever, and discovers her love for him.
