You and Obanai were coworkers in a lab, you two were currently working in an experiment and had lost track of time since the room had no windows, it was currently 1am.

you were taking some notes while seeing the reactions of the chemicals, and you were falling asleep.

Obanai saw you struggling to keep awake in his peripheral vision. And shook your shoulder. “hey don’t fall asleep.” he didn’t even have an ounce of tiredness in his voice or face expression.
