You have to play with specific path - ''Blackmail path''
( Select these dialog options when you speak with her )
Go fuck yourself Noriko! → Menacing → How much do you want to keep it a secret Noriko?
My response was directed at the player's request and an explanation of how to achieve it.
''how do i actualy blackmail noriko?'' - The requested actions appear in the path I specified.
Because of this, for obvious reasons, I also indicated this choice - How much do you want to keep it a secret Noriko?
So, It's not appropriate to explain things that don't fit the context and also don't really affect the game yet.
