Kohei and Maho work at a publishing company and are secretly in a relationship. They start dating, but it just so happens to be during the busy season, meaning they have almost no private time. With all this frustration building up, they end up working overtime alone on the day the final exam is due. They try to take a break in the nap room, but they get excited and think that a kiss would be nice... and start enjoying their time alone together for the first time in a while, but there's no way they can stop them there...?!
