Well, the cast did a lot of heavy lifting because the story is too damn scuffed. That wedding scene at the end was insanity! Who would accept such a thing?! Anyway, it's kinda a light drama from the leads perspective since they don't seek revenge. Instead, karma takes its course throughout the entire run. The drama separates the baddies from others for the most part, each carry on their story line without intertwining much until the later parts. Which makes it enjoyable watching the husband sinking into his demise very slowly instead of the usual quick payoff at the end. Although it's called Happy Sisters but they rarely ever interact or have scenes together. I thought we would be seeing some dynamic between them but there was none. The drama was fine for the most part and it's pretty much smooth sailing after the divorce.
