Yes, four years. Doukmei is still a mob underling working for some-one else. He always knew that Yashiro lied about not remembering him. That's why he willingly left, because he knew he/his love was a source of anxiety for Yashiro and he didn't want that for him.
They haven't seen each other in four years? And Doukmei is working for someone else in the mafia? Does he still think that Yashiro can't remember him?
