I'll never fall in love with a coworker... or so I thought!

Haru Ayakawa is traumatized by her break-up with her ex-boyfriend, but she signs up for a dating app after her coworker suggests it. When she decides to meet up with someone who she seems to get along well with after chatting on the app, the person who shows up is none other than her rival coworker, Reiji Shinohara! "That means I've been asking my coworker for advice about all about those embarrassing things..." As coworkers who joined in the same cohort, they knew about each other's pasts and have spent more time with each other than they had with their own friends. That's why Haru would never fall in love with one of them... Or so she thought!
