The scenario for the Harper-MC kiss actually writes itself: MC dominates the game after being brought in, Harper is overjoyed and jumps into his arms and kisses him, overcome by the situation.
A public kiss like that would be a huge scandal. Don't forget that right now faculty/student relationships are an extra big no-no because of stuff that happened before the MC arrived.
As for what I want to see most, event wise - I'd like to see the faithful route get some love on the scenes they've missed so far. Alexis, and the various women Rachel is helping get pregnant through the MC.
I'd also like to see the girls who haven't had any love yet be a focus, as much as I adore Jamie, Shauna, Bailey, Penny, and others who have been getting the attention, I also love Stacy, Jasmine, Kimmy, Rainn, Emiko... well, you get the picture.
I find myself a little more patient about the faculty members - Harper is awesome, so are Veronica, and Mabel, but as mentioned above, I understand why this can't happen right now.
Anyway, that's my two cents.
