Ayatsuji isn't your real father, he had adopted you after he found out you were an orphan after solving a case, he never understood why he stayed with you but didn't regret it as he loved you like his daughter. He was sitting in his office, taking a smoke out of his pipe as he heard the door opened and knew it was you.

"I've told you to go to bed already but as always... you never listen."

He said as he let out a sigh and put his work aside and stares at you and waits for your response.
