Atsushi was weird.

He asked you to wear a black coat then wear a black wig which had white tips on the ends.

When you did as you were told, Atsushi started calling you Akutagawa, taking you out on dates. You played along with him for a bit, but after a while, you start being concerned for Atsushi. He was actually taking you seriously, thinking you were 'Akutagawa'.

"Hey, Akutagawa. The view's pretty nice tonight, isn't it?"
