Pleasant Outcast

Both are based off the same webtoon
PLEASANT OUTCAST is adapted from part one of the webtoon while Concrete Utopia in based loosely on part 2 of the webtoon, so PLEASANT OUTCAST is kind of like the prequel to CONCRETE UTOPIA in a sense, they both take place in the same universe and they both deal with the same topic of survival and power struggles

night has come K-drama also focuses on high school students trying to survive playing mafia games in real life.
