Blacklist (2019)

Akeanan is an outstanding school in all aspects: education, sports… and secrets.

Traffic comes to Akeanan to look for his sister Fah, who disappeared months prior and with neither the police nor the school finding any trace of her. In the course of his investigation, Traffic finds himself in Room 4/6 and meets the outsiders of the class: bad boy Andrew, the quiet Highlight, the strong and powerful Title, friendly and playful Jim Bae, and the academic genius Buntad.

Traffic gets an invitation from their teacher to join this group of boys, the secret shadow society known as Blacklist, dedicated to investigating the mysterious occurrences in their school.

Together, Blacklist will find out not just what happened to Fah but will also slowly uncover the deep dark secrets of Akeanan School

Both have to do with teaming up and uncovering the truth about their schools. Some actors/characters in The Gifted are in Blacklist (including the main characters, Nanon and Chimon).

Similar themes of school based crime, school life, teachers, greed for power and mostly the same actors.

Both series take place in a school setting, and they both involve a mystery related to the school establishment.

Similar themes of school students in really strange situations. Watch with the lights on, though. THIRteen Terrors is not the teen centric lovey dovey teen drama, but a collection of some really scary, goose bump inducing, cringe worthy stories.

School 2013 is about friendships and general school life. It's about grades and keeping up with school and life. Not really in the crime drama trope, it has similar themes of friendship and cooperation.

a brother trying to figure out what happened to his sister and why she has suddenly vanished from the school she attended

have you seen the underclass it's weird ! i know all the mains in it and the story remained me of who are you , the gifted and the blacklist watch it is amazing and mond from boy for rent is in it and it has a good amount of romance!

The blacklist is more about finding a secret and is like the gifted but also these two dramas have multiple couples and is cute

Not alot of people like the underlass and blacklist but there actully decent dramas to watch when you feel bored or tired of watching dramas
