Habahiro Hige is a simple‑minded senior who works in an office and loves Tabekko Marshmallows. His routine often revolves around being mocked by his 24‑year‑old coworker Iori Wakabayashi, who exploits his fixation: from devouring them right before him to snatching his preferred brand at the convenience shop, and even humiliating him before their supervisor. While her friends cannot understand what she admires in him, she simply cannot shake his marshmallow‑like, fluffy silhouette. Whatever the effort required, Iori will discover a method to capture his interest.
Unbeknownst to Habahiro, she is attempting to lure him into a romantic bond with her. The path to a man's affection lies through his appetite, she believes. With a tote in hand, Iori keeps prompting him to chase her day after day, hoping he will finally perceive her intentions. Will he ever grasp that their connection could turn into a s'more? She believes that sharing sweets will bridge the gap, and each time she offers a flavor, hoping his curiosity will grow. Still, he remains oblivious to her advances.
