Wakaba Fukuda is a salesperson for an outdoor goods company, and she makes it her personal philosophy to be nice to everyone. But that ends up shooting her in the foot when her boss assigns her on a weekend product development project-slash-camping trip with Yaotome, her nerdy, stone-faced coworker from R&D. To make things worse, her boyfriend had just broken up with her on the very same day! The last thing Wakaba wants at this point is to spend her weekend alone with a boring weakling like him, but she catches a glimpse of his body under his shirt in the woods, and he's actually surprisingly jacked... As night falls and Wakaba finds herself ill-prepared for the cold mountain weather, Yaotome suggests they warm up the best way he knows how... by taking off their clothes and huddling up with each other! Surrounded by Yaotome's strong embrace and warm touch, Wakaba can't take it anymore!
