Behind Your Back (Modern Romance Yokai Flavored)

My coworker Nita seems to be afraid of taking a bath at night. When she's shampooing, she gets the feeling that something is behind her…… ※※※ Since I wrote this as a "countermeasure for bath horror," it's not scary at all. The genre is "low fantasy." And yet! In the comments section, people are saying "it was horror"?! Huh, seriously?! H-horror? Do I need to change the tags? W-well, if you don't like horror, please be careful. But it might be "romance" instead. Genre identity crisis.
