as Zemy said its kinda hard to actually find who you can dates, but if you mean like go on dates alone there are a couple.
Shopkeeper/Bernard has a couple but only in a few are they somewhat called dates.
Hayden has 2 that are for the most part called directly dates and also a cute scene that can have a "lewd" thing happen in it.
Korg technically has one, but it could be a hangout between friends that with context later counts as a date.
oh the latest thing with Othra and Roushk is def a date because of how its spoken of and the fact i have no other way of describing what the fuck it is lmao.
Arion has a date where you go on a walk through the forest.
Scrap has some scenes I would say are dates, like cooking with him and just hanging with him in general due to his actions they kinda feel like dates.
