Overall, you must have a bare minimum submission score of 20 to proceed with Desire. Choose all the options that are pretty much dominant/forceful and show that the MC knows what he wants, no hesitation (choices with ? at the end are bad). Follow the order of choices (which are highlighted as blue) attached to my comment to get the Desire scene and enjoy.
As for the correct option to avoid dying in the car accident, I'm honestly not sure. I had three options between taking my own car, having Gino drive me to school, or using Gino to drive Harmony's car with the MC and Melody to school. I tried to backtrack as far as I could, but all I can say is that you have to have Gino by your side to drive you instead. Otherwise, Kagney and Lacey will not find the bomb strapped to your car in time.
Finally, my thoughts on the update is that I enjoy this much more than the last update, since I felt the story was diverting too much and after damn near two years we are finally going to school. Not to mention, the women that were introduced in this update were far more pleasing on my eyes (Astrid, Mercy, Desire, Ivana, Koda, Miyoko, etc) than whatever those women were supposed to be in the last update. I can't believe there are over 80 LIs in this game now, jesus christ. I'm not sure how the developer will make time for these women.
