As with prior Bethesda games, the Starfield romance options you have to choose from are pretty clear-cut. All four of Starfield's romanceable characters are central to its mystery-driven plot, so it'd be hard to miss any of them as long as you progress the main mission. Once you meet them, you can have them join your crew and start to raise their fondness for you by choosing the right dialogue options.
As long as you carefully consider their likes and dislikes and spend time with them as your follower, Starfield's romanceable characters will quickly grow to like you. From there, you can start flirting with them and see where it takes you—which, in practical terms, is a special side mission and, eventually, a full commitment to the relationship through marriage.
