Isuzu Miyahara is an office worker who has recently broken up with her boyfriend. The reason is always the same: her strong sexual desires and a particular private preference involving plush toys.

Unable to find someone who shares her preferences, Isuzu's friend recommends a matching app designed to connect people based on their interests. After hesitating, she decides to register and begins talking to a man named “Fujikuma.”

But when they meet in person, Isuzu discovers that Fujikuma is actually Fujiwara, her junior coworker!

Determined to pretend the encounter never happened, Isuzu finds herself swept along by Fujiwara's words and eventually ends up going to a hotel with him.

A devoted and persistent junior × a senior with an unusual preference. As the two discover how perfectly their hearts and bodies match, their relationship begins to develop into something deeper.
