How to hide a topic/ask Monika to not bring a topic up again? HELP

[EColi07]

Title, I forgot what the hot key is and it isn't listed in the settings nor the full list on the official website.

Press X while the topic is in progress, and she'll ask at the end of it.

Thank you, but is it normal for this to not work with some topics? When I press X for certain topics nothing shows up, Monika doesn't ask me for topic removal at the end either.

What topic are you trying to hide?

[EColi07]

The "Natsuki's letter" one

You don't need to hide that topic as Monika will never bring it up again unless you ask her to.

Got it, thank you!
