Kachou wa Sore wo Gaman Dekinai

Saeki is a handsome section chief who excels at his job and is well-liked, yet he’s single. Everything seems to be going perfectly, except for one problem: he can’t help but notice his male subordinate Fujikawa’s nipples! Always cheerful and smiling, Fujikawa’s nipples are visible through his shirt, and when they get damp with sweat, they become even more pronounced—making them hard for Saeki to ignore. But why is this happening? He’s neither gay nor does he have a nipple fetish! Fujikawa is a natural airhead, and when Saeki suggests he wear an undershirt, he completely misses the point. To make matters more complicated, they are scheduled for an overnight business trip together. Can Saeki resist the temptation of those distracting nipples?
