Favorites/Thoughts on the Datables? (Both on/off routes)

[Gamer]

Just played the game again and I have some thoughts:

1. How would Grabiner know I kissed Pastel while married to him? I know it loses a lot of points with him but he doesn't seem to treat me any different.

2. How come I don't get a response when I send Minnie, Donald and Damien romantic valentines when not on their path or having turned them down? I should at least get weird points or something.

3. Does it really make a difference who I give my plate to at the Maple Ceremony?
