Well, it's not like they haven't been doing anything romantic at all. They've been doing lots of things that are romantic...for them. Some of this has been Tomo trying to adjust to being more "girly" herself. She's only ever been a tomboy so it's new to her too. And she keeps getting pulled back into tomboyish roles like the Handsome Prince(ss), then having to process that she could have been a good Cinderella too. I'm glad they're taking it slow.
Besides, once they become an official couple, the story's over, right?
