While Angry Mom and God's Gift - 14 Days don't sound similar in synopsis, the feel of these dramas is very similar. Both of them have a plot that delves into corruption and how it trickles down into society and has an effect on everyone. With both dramas, you get the feeling that there is a lot happening behind the scenes. Also, both feature a mother having to resort to desperate measures to protect her daughter.

Both dramas focus on bullying and the darker aspects of high school in Korea.

Both are dark and gritty dramas with a similar feel to them. They both have unconventional protagonists who are criminals/involved in the underground criminal world and deal with organized crime, are filled with action, and contain interesting plot twists throughout the series.

Both darker human dramas by Nojima Shinji that are difficult to stomach and get through for many. While the plots are different for both, both focus on darkness within people and the aspects of humanity most people would rather look away from. Both have a very similar feeling to them.

While the plots are different, Sakurai Sho plays in both of these dramas as very similar characters. Both characters are eccentric and have very similar mannerisms and catchphrases (Iiii neeee~ vs Nantsutte~) and both have dark secrets they are hiding. If you liked Sho's character and acting in one, you will enjoy him in the other.

Both dramas focus on extreme bullying in school and overcoming it. While Who Are You: School 2015 has more romance involved and more of a story outside of the bullying aspect, the feel of these dramas reminded me of each other.

Both are dramas with the same kind of psychological game show format where people have to face themselves and their true selves are revealed to the public. Both involve a complicated connection between the characters that is revealed over time. They also have the same kind of pacing and the villains remind me of each other.
