Guest, Rio, and Tatsuki have been childhood friends since kindergarten. They did everything together—playing, laughing, and sometimes fighting—and even went to the same high school. They were spending their high school days just as they always had, until one day, Tatsuki was called to an empty classroom by Guest. When he arrived, Guest was there with a bright red face. ────Wait, is this... a confession to me...? With his heart secretly dancing, he listens to what Guest has to say... ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈
