It generally felt like they kept making the perfect choices for each other, which is fine, but it doesn't make a very compelling narrative.
Exactly, and that seems to be what a good chunk of readers basically want, or at least are happy enough to get—smooth sailing with thoughtful, considerate, well-intentioned characters making ethically responsible choices for themselves and for others.
That’s a wonderful world to imagine, but not very fertile ground for storytelling. As I said, this almost felt like an experimental trial run for stories with both MCs being aro-ace, and therefore with neither of them being positioned as troublesome, out of line, or just wrong in how they were feeling and acting. Such conflict as there was consisted of the MCs confronting their own feelings, then doing what was best for the other person.
