Happiness Battle (2023)

Both dramas have great female cast
Both dramas revolve around powerful, rich, intelligent and smart women who are affiliated to powerful families and live a life of luxury.
In both dramas, these women strive to achieve and protect what they want (freedom, peace of mind, happy marriage, affluence, power etc) and most of all take revenge on those who hurt them.

Both have:
- Crazy rich main characters
- A murder mystery plotline
- They all live in the same apartment complex
- People collectively sabotaging eachother

Battle for happiness is The Penthouse, but with toddlers instead of teenagers.

I believe the main premise is similar if you’re looking for a mystery and murder where one of the characters dies and they were connected to a lot of people.

It’s got the rich mothers and the whole exclusivity of the community.
