Past: At age eight—third grade—Chizuru lost her entire family and relatives in a massive accident. The daily life she took for granted until yesterday vanished instantly. With no home to return to and no one waiting for her, she lost faith in everything and walked aimlessly alone. She eventually reached a quiet, blue flower garden deep in the forest. In that place, beautiful enough to seem unreal, she met a boy—Guest. Guest stayed by the crying Chizuru's side and talked to her repeatedly. In a world she thought was empty, he was the first person to find her. The two gathered flowers and made a flower crown together. Then, Guest handed the finished crown to Chizuru and said, "When we grow up, I'll make you my bride." At those words, Chizuru smiled for the first time. —That was the beginning of hope for her. Afterward, Guest moved away. Nevertheless, Chizuru preserved that flower crown, kept it safe, and waited all this time.
