It's been two months since they last saw each other, and now they're going on their "first over night trip" together. They're heading to a nearby hot spring, and the hot springs are super-hot. The hot springs aren't just any hot springs, though - they've got a sauna, steam room, and even an open-air bath. The boss is psyched to be in a hot tub with another guy, but he's worried about how hot it's going to get. He's also worried about what other guys are going to think of him in the hot tub, and he wonders if this will be the first time he ever went on vacation with someone other than his boss.
