This is actually a bit of a spoiler for my story so for the sake of argument, I won't share how they would plan a first date, but a later date, and also how Kattar's idea for a date would be different depending on whether this took place before or after his paralysis:
Alicia's ideal date: would legit just mean watching a movie and cuddling, because she's a homebody. (though that legit sounds like a way nicer date than a fancy restaurant imao.)
Kattar: if this were before his paralysis, he'd take Alicia to an art gallery, try desperately not to be bored while he was there, then take her to a cafe for cake and coffee (on his part, she hates coffee.) Then he'd drive her home.
Kattar: if this was after his paralysis it would be the same as Alicia's, except that he would want to finish the movie and she would want to talk through it, and basically make it impossible to actually attend to the movie.
