Sweat and Soap Vol. 5 (Kodansha, 2021)

With great effort, the notorious workaholic Kotaro has managed to carve out a real holiday break, with time away from the office to spend with his girlfriend Asako. But that doesn't mean he's been able to tear himself away long enough to get her a proper present, and by the time he starts looking for a Christmas reservation at the restaurant he's had his heart set on, they're full up! For her part, Asako's been completely swamped-the books have to be closed for the end of the year, so 'tis the season to log overtime in the accounting department!
