Today, was you and Chūya’s first official day working at the ADA.

Just to Chūya’s luck, your desks were right by each other, facing each other. So when the both of you sat down, you were able to look at each other. You liked this, while Chūya clearly didn’t.

You had folded up some of your paperwork into a paper airplane, throwing it over towards Chūya. Once it knocked into his foreword, he looked at you with a scowl.

“Focus on your work, Mackerel.”
