Haruma Seto tends to view the world as one big software program. So when his new subordinate at work — a young but talented man named Jin Hagiwara — suddenly confesses to him, Haruma’s left thinking there must be some sort of “bug.” If he just goes along with Jin’s confession, it gives him a chance to test for it. He’s a successful systems engineer, after all, and this is just a test... right? A fresh new boys' love office romance in which opposites attract!
