His determination to overcome difficulties allows him to quickly adapt to this change. Then, on a bright and sunny afternoon, in an effort to apply the idealistic Japanese youth lifestyle gleaned from manga, he confesses his feelings to the school's unattainable beauty, Yukino Yukinoshita, but is rejected… What will become of the disheartened white-haired girl…? Seeing the white-haired girl gradually surrounded by others, an anonymous Yukino thinks: I'm starting to regret it.
