That's a tough question because the answer keeps changing over time.
For me, the romance must be at the core of the plot. I don't want any gimmicks or overly complicated subplots. That's why I prefer slice-of-life stories.
Right now, I'm hooked on Lily Love 2 (I'm rereading it). It's a great romance with smut.
I also hold My Dearest Nemesis dear to my heart. It's a great romance with nice development.
