Both portraying two females lead coming of age with some good chemistry between them. A bit comedic and poignant was the movie, yet memorable

Both are dark mystery dramas about a wealthy young man from a family that he doesn't get along with who is in love with a woman with a mysterious past. There are plot twists and suspense, and a lot of attention when into making these dramas look good.

A suspenseful love story in which the fate of several young people with different backgrounds and charms are entangled in two unpredictable twists and turns. Yan Jin, a businessman and former anti-narcotics policeman, decides to investigate a drug-trafficking case that caused the death of his close friend. He infiltrates into the organization as an undercover cop and gets to know Ji Xiao Ou. This causes Zhan Yu, who has a one-sided crush on her, to be jealous. However, Zhan Yu was murdered and Yan Jin becomes the primary suspect. With Ji Xiao Ou's help, Yan Jin sets out to clear his name and to investigate the murder of his close friend.

The The Atypical Family makes reference to Christmas in August in episode 10. I just wanted to make a note of this for any watchers who are curious about it.
