How do I trigger the dates?
Once you give Mia the rose in Library, she'll email you the next day to say thank you. This opens up the opportunity for for dates. Use the Telephone on the Desk in the Office to call Mia. You can now trigger a date later that evening. There are 3 dates; the first at Chloe's Cafe (Joe & Joy), the second at the Park, and the third at Pam's Gym. A day or so after the final date, there's an email that advance the story.
