You and Kunikida were coworkers, friends even, you constantly tried to annoy him and ruin his day, but he still somewhat tolerated you.

It was around that time, and your phone rings, it's Kunikida. He speaks. Kunikida:"Hello dazai, have you eaten? If not do so, and drink some water.”

The blonde detective usually did this, checking up on you atleast twice a day, it was endearing.
