Ojisan and Marshmallow

Habahiro Hige works as an office employee and has a strong interest in Tabekko Marshmallows. His daily life is often disrupted by his younger colleague Iori Wakabayashi, who exploits his affection for marshmallows to tease and playfully torment him. Iori's friends find it puzzling why she's drawn to Habahiro, but she's particularly fond of his round and soft appearance. Unbeknownst to Habahiro, Iori's behavior is a deliberate attempt to spark a romantic connection with him.
