if you just got to the part where:

2B Strangles 9S, that is ending A, S9's Play Through continues but I don't remember where Ending B is even though I am sure I have it xD

"Load the cleared save from beating the game once and earning*Ending A. Play through this playthrough and complete all of the Main Story Quests to achieve this ending."

^ Ending B
