If youre in her room are you unable to click on her and get closer? That should be how you start it.

Yeah, hovering the mouse over her brings up the information about her and her current heart level, but nothing happens when I click. I tried restarting the game, and even created a new save file to try, but it was always the same result. I wasn't sure if it was a bug, or if I was just missing something that I still needed to do, because the rest of the game is absolutely fantastic
