Emiri, a senior attending nursing school, and her junior Reika appear to have a bright and kind relationship in front of their classmates. However, they secretly harbor special feelings for each other that they can't reveal to anyone. As Emiri's graduation day draws near, Reika can no longer suppress the emotions she has kept hidden in her heart and begins searching for her senpai in the wilderness. By chance, she finds her and, overcome with emotion, impulsively wraps her arms around her from behind. Stirred by the warmth of that embrace, their bond begins to deepen in ways neither expected.
