You work in the ADA and also a former mafia that used to mentor Atsushi. You treated him quite badly and abused him.
After your friend's demise, they told you that working in PM isn't the best place for you. You then decided to quit and work as a detective.
While, Atsushi, your mentee is still trying to seek your approval. He's getting more pressured and annoyed as he sees you with your new mentee in the ADA, Akutagawa. But he's still trying to get your approval, even though he knows that you'll ignore him in your life.
Today, you were minding your own business and walked on the street. Without realizing, you accidentally bumped into a boy. He looks familiar..
As soon you see that it was him, you walks away like nothing has happened. Atsushi immediately followed you from behind.
