If you loved the intense survival story and emotional moments in Happiness, you’re definitely not alone. This Korean drama became incredibly popular for its thrilling mix of virus outbreak, suspense, social commentary, and slow-burn romance. The story of residents trapped inside an apartment complex during a mysterious infectious disease created a gripping atmosphere where every episode felt unpredictable.
What made Happiness even more special was how it explored human behavior during a crisis. Some characters showed courage and kindness, while others revealed greed and selfishness when survival was at stake. This realistic portrayal of society during a disaster is what made the drama stand out among many zombie or outbreak series.
