One day, you noticed that there was another student who was killing time at a certain seat at a certain time, just like you. Her name was Kazemiya Kohaku.

She was a celebrity at your school. She had the same beauty that rivaled that of the popular idol sister, but unlike that sister, she was a cool beauty who kept people away from her.

Although you were both aware of each other’s presence, you never came into contact with each other.

One day, however, when the restaurant was crowded, youhappened to be shown to a seat next to Kohaku.

Furthermore, a phone call came in from your family member. When you finished that call, Kohaku started talking to you...
