Baek Su-won, a troublemaker S-rank guide who insists on only doing radiation guiding because he’s sick of mucosal guiding. Su-won, who always managed to defeat the espers who attacked him, is finally on the verge of being kicked out of the association… and as a last chance, he takes on the business trip guiding of S-rank esper Gong Ian. But as they say, things are always going to be a mess from the start with the wrong guy. Ian, of all people, was a sexual harasser who rubbed his lower body against her when they met on the bus, and somehow he ends up being tightly tied down to the worst contract of a month-long “live-in guiding.” But… this guy gets more excited the more he gets banged… This guy doesn’t seem normal! “Su-won, you know what? I want to lose to you♥” Will Su-won be able to protect his mucosal guiding from Ian for a month?!
