Clearly that's what I did in all my playthrough, but it is annoying that there's no clear indication as to what actually starts the romance. Same for Halsin who comes out of nowhere with his advances with no prior indication from the player about their willingness to start a romance.
Larian needs to fix the triggers and flags for romance. Some of the dialog options are not clear as to whether they are just friendly or a romance starting flirting. DAI had a clear option marked start romance, would be nice to have that sort of marker in BG3 as well.
