Mou Ichido, Shitemitai.

Overview

Inugami, a strong-willed office lady, and her colleague Sarushima are always fighting. As usual, the two spend the night arguing at a bar... and when they wake up, they find themselves at a love hotel together!? They don't remember why they went there, but their bodies remember that it felt amazing. (Source: PinkPineapple, translated)
