Netflix has been on a roll this year with thrilling original Korean dramas, and its latest must-see K-drama, "Hierarchy," combines the life-and-death shows of "The 8 Show" and "The Glory" with the rich kids gone bad atmosphere of "Gossip Girl" So says the seven-episode drama, which arrived on Netflix on June 7, about the drama that abounds in the halls of Joshin Academy, a super-elite high school that educates the 1% of South Koreans. It's "no Constance Billard St. Jude without Little J or Dan Humphrey," but at Josin, scholarship kids can face deadly consequences when they become popular bad guys.

Season 1 of "Hierarchy" focuses on the arrival of Kang Ha ("Crash Course in Love" actor Lee Chae-min), a confident, brainy kid who enrolls at Joshin with the mission of finding out who killed his identical twin brother In-han (Kim Min-chul). At the end of the show, In-han's killer is revealed, but a shocking mystery still remains for Josin's students. Read below for everything you need to know about a possible second season of "Hierarchy."

When Kang Ha first arrives at Josin Academy, his first suspect is Kim Lian (King the Land's Kim Jae-won), the most popular student at the school and heir to the Josin Group (aka the conglomerate that owns the school). Kang Ha's younger brother In-han was relentlessly bullied by the popular kids for disrupting the school's social hierarchy by daring to be friends with Ri Ahn's girlfriend, Jay (Ro Jung-ui from "The Summer We Loved"). In Ha was eventually killed in the hit-and-run incident that opened the series. However, Li An publicly discloses her own involvement in the bullying, but it turns out that bullying was not the cause of Inha's death.

On the night of his death, In-ha was running down the hallway of Josin to escape his tormentors when he found Ri-an's best friend Woo-jin (Lee Won-jung) making out with Ji-su (Byun So-yun), one of Josin's teachers. Ji-su was desperate to keep her relationship with her student Woo-jin a secret, but In-ha, badly beaten and emotionally scarred, kept running away. After In-ha stumbled in front of Ji-su's car, the teacher took In-ha's cell phone and camera pen and recorded the night leading up to the accident. Jisoo did not call an ambulance and left the student to die.

Woo-jin later finds the cell phone and camera pen in the car Ji-su was driving when she hit In-ha. By the end of the series, Woo-jin is inspired by Jay's attempts to take responsibility for the violent system at the school that led to In-han's death and subsequent cover-up. Woo-jin gives In-han's pen and phone to Jae-jae, who gives them to Kang-ha, who turns them over to the police as evidence. The students who beat Ji-su and In-han are quickly arrested, and those involved in In-han's death are brought to justice. [But nothing changes at Josin. Sure, there is a new principal, but the administration will remain at the mercy of Li Anh's parents. This is evidenced by the shocking final scene in "Hierarchy."

After the credits of the "Hierarchy" finale roll, the post-credits scene shows a typical day at school, with Kang-ha walking down a crowded hall and Hye-ra (Ji Hye-won) dancing in the classroom. But the nimble girl stops when she spots a dead body lying in a pool of blood. Seconds later, an alert arrives on Li-Anne's cell phone as she enters the classroom with the corpse. Seconds later, an alert arrives on Li Anh's cell phone as she enters the classroom with the dead body. The new anonymous text message reads, "You seem upset, Kim Lian," and Li Anh looks straight into the camera, the screen switching with a big cliffhanger to the (possible) future of the series.

No word yet on whether "Hierarchy" has been renewed and will return for Season 2. The teen drama has only been on Netflix for a few days, and the streaming giant often waits at least a month for ratings before deciding to add episodes.

There are several good signs that "Hierarchy" Season 2 is about to happen. First, the presence of a post-credits cliffhanger means that there was at least the possibility of extending the story in the minds of director Bae Hyun-jin and screenwriter Joo Hae-mi, who produced season one. Furthermore, "Hierarchy" would not be the first Netflix K-drama to be renewed, even though it was originally slated for only one season. (See "Love Alert," "Sweet Home," "D.P.," "Death Penalty for All," and of course "Squid Game.")

In terms of ratings, "Hierarchy" appears to be an early hit. The teen thriller is currently in the top 10 in the U.S. on Netflix and is already racking up numbers (and lots of fancams) on TikTok. Stay tuned for news on the fate of this K-drama in the coming weeks.
