The first part of the game does not affect this choice up until your getaway vehicle is ambushed and falls off the bridge.
At this point, you have the option to go to the police or Woe' s.
Go to his place and finish the conversation. Agree with May-Lings plan afterwards and go to the hotel. At the hotel when the phone rings, the Tchois are there for you.
Let the scene play out and choose the window option.
When the window doesn't open, do not break it, choose the other option and the goons will kidnap you.
You will be in the interrogation scene. Keep protecting until a point where you have the choice to save yourself. May-Ling will get stabbed and she will say that Parr has the bowl.
At the end of the scene, you will be kicked outside. Your character will head into an alley and see some guys there. Fight them which will not trigger the hospital scene. You will go to Parr's place.
At Parr's place, do not attack him, just intimidate him. He will go for the safe. Tell him you want to open it yourself. At this point, you will open it and see a gun there. You will pick it up and Parr will tell you that he will give you an offer of 1 million pounds to not tell the Tchois.
Agree and the achievement is yours. This also triggers another ending where you go and get the bowl with Parr at Hainsworth's.
