OK Razor,

We (you) are going play with these two for a while so lets not make Juliana that easy.
How about we cut off the last 280 odd words and leave the professor a bit frustrated.(just a touch of a rewrite) Next we switch to a more feminine perspective that will end in Julia's shocked refusal and flight from the dinner date. Start with her enthusiastic hopes for the evening, her growing concerns as he makes his move and end with her utter dismay.

Use her character sketch to do this and expose more of her character as you develop the theme.

Yes you're right we'll need to add to the begining too but we'll get to that in time as the characters come more sharply into focus.

Till then
