hope you don't mind that i peeped the above details! i love a cast cliche line, but i always want to reassure that i'm not one to force a romance based on the show. nina was raised by a single father and thought she was the product of a surrogate until recently. so they at least have some family conflict to bond over if they find reasons to open up to each other. if his dad happened to live in the same neighborhood as she did growing up, that would be a super easy point of connection. or they could have met more recently. she wouldn't know the first thing about surfing, but she's a movie buff and might like to either listen to or perhaps even participate in the musical side of his life!
