Two friends, Kyung Min and Detective Jong Suk, reconnect after receiving a message from a friend they haven't heard from in 20 years. The message triggers painful memories of their school bullying, and soon after, a series of mysterious murders begin. As Jong Suk investigates, he uncovers connections to the past, while the drama explores the origins of school violence and its enduring impact on society.





If for some reason you're looking for very dark dramas with revenge plots, I believe King of Pigs and A Christmas Carol have it. These two are similar as they deal with: hardcore bullying, s*xual assault, and other violent themes.
Aside from the aforementioned, both contain a revenge story. Whilst Kyung-min avenges his lost childhood in the King of Pigs, Il-Woo attempts to try and fight for his brother's death in A Christmas Carol.
Both have characters with mental disabilities, though they differ.
I believe these two films should have warnings of their own as they're both mentally torturing to watch, and are embedded in your head forever. I highly advise that you take precautions and only watch either one of them if you're truly mentally capable, as I had nightmares after finishing King of Pigs.

Two friends in the past were victims of serious school bulling. One could not resist his trauma, and becomes a serial killer, walking in the path of revenge. Another one tries his best to overcome the trauma and becomes a police detective. He now faces tragic fate to risk his life to capture the serial killer.
