I recently stumbled upon 'My One and Only' while browsing for new dramas to binge, and I had the same question! From what I gathered, it’s a standalone romantic drama—no prequels or sequels attached. The story wraps up neatly by the end, which I actually appreciated because so many shows nowadays drag things out unnecessarily. The chemistry between the leads totally carried the show, though! It’s one of those rare gems where you don’t feel like you’re missing out on a bigger universe.
That said, I did some digging, and some fans have joked about wanting a spin-off for certain side characters. There’s this one quirky best friend who steals every scene she’s in—I wouldn’t mind a mini-series just about her antics. But officially? Nope, it’s a one-and-done deal. If you’re looking for something similar in tone, though, I’d recommend checking out 'Romance Is a Bonus Book'—it’s got that same cozy, heartfelt vibe.
