You don't need it.
You just need to go to the Reminiscence Room, that can accessed on the menu's Memories (Below Option and above Save), but before that; clear the first event/sex scene with Arika before you can get the option, as it will given to you by the old man from the village.
To speed through the text fast without holding a button, press S then the whole thing will pass MUCH faster until you can move your character or the scene shifts to another location/scene.
Once you are in the Reminiscence Room, talk to the cat and all events will be unlocked.
If playing the 1.1 version, then some of them may not be unlocked, but that's intentional, as it's only a demo, as in they are in game but not ready.
