This drama made me look at happiness in a whole way. I loved each siblings unique perspective on their situation and how they interated with the people around them. Figuring out Mr Gu was quite fun (it helps that he has this mysterious sexiness).
It's interesting to think about how much we fake or hide our emotions. We all need to be liberated from something, but we might be to scared to admit it.
The romantic in me is a little dissatisfied with the ending. My wish or interpretation might be completely off. I like a solid or blunt ending.
