I kinda don't remember much about the plot but I feel like this is a female version of prison playbook...

The stories aren't similar, but the filming techniques are alike and both have the same type of feeling.

The stories are both just moments of high school life with small details and no big plot points. The directing for them both is amazing and symbolic.

Even though this one doesn't have supernatural elements I felt similar vibes; there're mysteries of the past to be untangled, it deals with heavy themes and there're some mind games regarding the reveal of the culprit, the OST makes you equally melancholic... You might give it a go and perhaps enjoy it :)

Both pioneered the whole "america remaking asian horror" films in the early 2000s and both are about a vengeful female spirit set out on attacking anyone who crosses them. if you've seen the american version of either films you need to watch the original. they're so much better.

Similar concepts where a king travels to the present. Though the king in My Assassin Girlfriend seems to be more intelligent when it comes to navigating the modern world.

Similar vibes and concept. A king traveled to the present. My Assassin Girlfriend seems to focus on less characters so the plot may be easier to follow.

The prequel to this so obviously a must watch. I think it's best to watch in order. This time, more ppl come over from the past

Both have a blind female character and the male character also have something to hide from his identity.

Both follows the lives of an aspiring actor/actress, who starts off as an extra. They continue to persist despite the set-backs that they meet.

Gritty. Amazing action. Solid acting. Bromance heavy. Main lead Taemin becomes the killer's target and Park Hae Jin gets similarly affected in a different way.

Awesome action, unique camera, work both are extremely gritty and emotional. Both have emphasis on male relationships.

A bit different genre wise, Final Life has a more scifi element and Cruel City is very much a noir gangster story but the similarities are in how neither of these shows are without flaws but they get to you and don't let go. Both are more bromance heavy. Both have phenomenal action. Both have messed up characters with traumatic backstories. Both will leave you a crying mess.

Genre wise Final Life has a scifi element and its artistic but more emphasis is given to the two male leads and their relationship and on the crime just like Hello Monster. In Hello Monster the two brothers Seo In-guk and Park Bo-gum go through hell because of a serial killer and its such a sad, heartbreaking story when Seo In-guk realizes that his own brother is the killer. He's torn between having to protect him and sending him to prison. In Final Life Taemin is the one who went through some torturous medical experimentation and is assigned to Shota's unit to solve a crime but ends up being the target of the killer himself. Shota the cop in the same unit who lost a younger brother at a very young age, and still thinks he was responsible for the kid's death. So when he finds himself in the role of Taemin's protector, he will go to any lengths to do it even if it's 'wrong.'

Both are scifi stories about traumatized characters and human experimentation elements in Taemin's arc are also in the brothers story in Circle. Both have characters who suffer immense loss with traumatic backstories. Both have more emphasis on the bromance. Final Life feels like a bad dream, very artistic, definitely a must watch.
