Kagetsu Confusion, A little clarification on the mysterious girl... Options

[Ronin19]

I don't know if anyone knows this or not, but I looked at the wiki for this game, and it says that she only has 3 heart events and can only be triggered by giving her a certain ammount of gifts, same for her proposal.

Event 1: Must have given her 30 gifts.
Event 2: 50
Event 3: 80
Proposal: A total of 120.

I think you can't give them to her all at once, I think it must be done individually. Sorry if this has been mentioned before ^^;
