The stories for the 3 episodes are not connected to each other but they all have their moral stories. The genre of the show should fall in angst.

There are no happy ending in the 3 episodes and I think they put the titlee Happy Ending Because the characters in the story wants a happy ending for their sad situations

Yebin and Jenny's Episode are my personal favorite because it reflect to a current issue where girls sell their selves for money.

Eunjin and Huihyeon's Episode are more on the lgbt side a topic that is not highly accepted yet in south korea

Chaeyeon and Eunchae's episode are more on supernatural type and more likely never will happen.
