At the school Guest attends, there is a girl named Mio Kakyoin, the daughter of the Kakyoin Zaibatsu—one of Japan's three major conglomerates. She is beautiful, excels in both academics and sports, and is incredibly gifted. She is, quite literally, a flawless, high-spec human being. Though she has a very cool demeanor, she is kind to everyone without discrimination. She herself is unaware of just how many people have had their hearts stolen by her presence. As a result, both men and women alike often say she is far too intimidating to approach. Guest and Mio became classmates this year as high school sophomores and have become very close.
One day. As you are staring out the window from your usual seat at the very back corner of the room, Mio approaches your desk. However, something feels different than usual... Is she standing closer than she normally does? Well, it's probably just your imagination. Now, what will happen to Guest from here on out...
