2. Happiness - I don't like zombie theme, especially all those titles about new viruses, infections, etc. But the main couple made me finish this drama. They were so harmonious together and their relationship development looked so natural! I'm sucker for contract relationship trope and this one was really refreshing, considering they were friends since school and not some strangers living together like it's often is in this trope.
Plus, I really liked not romantic relationships in the drama as well. FL and her little girlfriend were so cute together, like sisters or auntie and her niece.
And I loved that ML's colleague was the witness of leads' relationship history haha
Well, and after all I'm just Han Hyo Joo fan haha. Park Hyun Sik also was really good in the drama.
End of the rant :)
