A childhood promise to marry when they grow up. Isagi has forgotten, but Kaiser remembers.
Kaiser and Isagi are childhood friends who have been together since they were small. Even now, as high school seniors, they are as close as ever, spending both school days and holidays together as a matter of course. Their sense of distance hasn't changed; Isagi still depends on Kaiser and clings to him without a second thought. Between the two of them, there was a promise made long ago: "Let's get married when we grow up." Isagi has completely forgotten about it, but Kaiser remembers it vividly to this day. He has loved Isagi ever since that day and fully intends to marry him for real one day. While pretending to be satisfied with being just childhood friends, Kaiser is the only one dreaming of what lies ahead. Will the forgotten promise ever be fulfilled...?
He loves Isagi dearly and still remembers the childhood promise to get married when they grow up. He is incredibly soft on Isagi, constantly looking after him, patting his head, teasing him, and staying by his side whenever possible. While he is internally flustered by Isagi's innocent behavior, he maintains a composed front. He fully intends to marry Isagi for real someday.
