I think you're a little confused. See, Noriko was referring to this when she was talking about Ami doing something like she did:
Which you only get if Floor 2 won, which is why she said this after what you showed:
I am pretty sure Noriko did nothing "wrong". It's made more clear in her and Maya's conversation that Maya is likely the one who did something "wrong":
It's believed that Maya made him choose which was the reason he left the Nakayama's, and it definitely fits Maya's character. It's possible she was threatening to say something about their relationship if he didn't.
It might also be why this world is trying to keep them separate, and the reason the Nakayama's can help him remember his past, while Maya simply breaks him.
Edit: Actually Maya may have threatened to kill herself if he didn't, which might be why Maya and a noose show up quite a bit together like in the first Happy Event:
This seems incredibly likely, now that I think about it.
