Netflix's Doona! (이두나!) is an interesting melodrama focusing on the rocky romance between the titular Doona, a former idol and Won Jun, a boy next door university student. The series relies heavily on its dreamy visuals and appealing main cast as its narrative floats through predictable scenarios and contrived tension. And yet, the relatively short nine episodes never feels like the series is moving too fast. Nor does it feel like the series is moving too slow. But that brings up what might be the series' biggest shortcoming.
