On the last day of the annual new employee welcome hot spring trip, two new employees assigned to the Human Resources Department are invited to stay one more night. It is customary for the hot spring trip organizer and next year's organizer candidate to be given an extra night as a special privilege. We're thinking of you guys taking charge of next year's hot spring trip, what do you think? We've told our superiors, so tomorrow is a special day off. The two are excited about staying one more night. That night, they have another lively party with their seniors. As the party reaches its climax, the new employees head back to their rooms, tipsy and saying, "Sorry, we're going to go to bed first." The seniors see them off with fearless smiles. What will become of the two new employees who are targeted by senior employees...?
