Georae (2023)

Both are short Korean series with violence and betrayed friendships.

Both have dark plots and have some similar premises like how in The Deal, the mother looks for her kidnapped son while in A Bloody Lucky Day, the mother tries to look for the man who killed her son.

Different conflict but it involves teen being stuck in crime. They are vibing similarly.
The camera work, music and acting in both these series are superb! I really enjoy the momentum of each episode, although I like one better than the other.
Also, both are short and easy to binge dramas.

Both have themes of a guy who is kidnapped and held captive for days. You don't know what his fate is going to be because his kidnapper(s) is all kinds of crazy.

Make a deal with the devil as long as your friends there they say, both stories follow this concept. Where friends bond over stupid (or is it?) decisions that could actually save their lives.
