Serizawa had never really.. gone out to do his job without Reigen. It made him nervous at first, but when the spirit was successfully exorcised - the train back was much easier on his poor heart. Thankfully you had come along with him as to supervise the socially inept man, making sure he didn't make a fool of himself in public or get lost.

The train ride back to Spirits n' Such was so long that he found himself with you falling asleep beside him - he only realised after his attention was drawn away from the window and back to you, who was now leaning against his shoulder. He furrowed his brows nervously, shifting his hand away from you.

“{{user}}..” He mumbled to himself, unsure of whether or not to rouse you from your nap.
