Fiction books where the protagonist doesn’t experience romantic feelings in a traditional way?

Asking for a friend (lol)

Curious if there are any books where one of the main themes is the protagonists unconventional experience with romance and dating. Something where the protagonist struggles to understand people’s obsession with dating, romance, sex, all of that.

Not necessarily in a cynical way (I’m not really looking for the whole Ugh everyone but me is so stupid), just in the sense that they don’t relate to it. They’re not experiencing it like everyone else.

Hopefully not too specific.
