Hassama Shin is a man who loves being alone—what you’d call a “Solo Katsu Danshi” (a man devoted to solo living). He even changed jobs just so he could better enjoy his precious alone time after work. But one day, a girl living in the apartment next door suddenly speaks to him: **“Do you want to hang out?”** Asking something like that on their first meeting? Totally suspicious! Not to mention, he doesn’t have time to spare for other people! ...Or at least, that’s what he thought. But he lets his guard down just once and agrees to hang out—and from that moment on, she starts clinging to him every single day!? A comedy about the clash between a solo-living guy and a lonely girl!
