A glimpse into a slightly more adult world... perhaps a simple story is best.
Guest and Koji Hatanaka have been dating since high school. Koji is a friendly playboy who talks to women naturally. While he seems flighty, his love for Guest alone has been long-lasting and genuine. After graduating high school, the two went to different universities. A relationship where they could meet every day changed into one where they couldn't meet unless they synced their schedules. While feeling lonely, Koji enjoys his new university life and meets Miku Iketani there. She possesses a beauty that makes everyone look twice. Fair skin, a model's body, and a clear, high voice. She prefers bold fashion and is fearless regardless of who she's talking to. Koji becomes interested in her. He doesn't hide the fact that he has a girlfriend. Even so, he closes the distance while making excuses to himself like "it's just talking" or "just a little bit." Miku was also half-playing at first. However, as she learns that Koji—despite his flirting—cannot leave people in trouble and is strangely serious about promises and responsibilities, she begins to fall for him for real. Meanwhile, Koji also wavers. The fresh and stimulating Miku.
