It just is tho, like the romance, the action, everything about it just books. I loved both, waiting on season 2 from a Korean odyssey
Its kinda the same and they are both my fav dramas of all time. They are similar bc they both have a bunch of residents in an apartment and a murderer and its like just the best, i cant explain it. Happiness has a strong and independent female lead with an amazing male lead by her side(her husband) and this drama will have you jaw dropped, laughing, crying, mad, etc. It will take you on a roller coaster of emotions but they are both good, 10/10 both of them. i recommend as a girly who loves crime, mystery, psychological, This drama (Happiness) is my number 1 fav drama and strangers from hell is my number 2. If i could put them both at number 1, i would. I recommend with my whole heart.
