Remember-Member (2022)

Not only are the titles similar but they carry a bungee of similar aspects like
Psychology, horror, mystery, and thriller.
They both take place in a high school setting with the characters not feeling like they fit into the world around them.

Both the series and movie tells a story about teens in school playing a death game in order to survive.

Though not immediately similar, both titles have a lot of gore, have developing friendships (and slight romances), and involve a lot of running around in school to avoid getting caught by monsters. Not to mention both are great watches!

The story is very similar, when midnight arrives the protagonist finds herself back at school (in a dream). She's not the only person there. Her childhood friend, Takahiro, and four of her classmates are there, they find themselves in a loop and try to find a way out.
There is also a brief romance between the protagonists, the only thing different about the series is that it is a horror genre.

Sakakibara Koichi is a 15-year-old boy who’s forced to move to a suburban town in the mountains to live with his grandparents in the spring of 1998. One day, he suffers a seizure brought on by a chronic lung condition and collapses, but luckily he’s taken to the hospital in time to save his life. While in recovery at the hospital, he sees a beautiful girl wearing an eye patch and becomes fixated on her before she makes an odd remark about the morgue on the second floor and leaves suddenly.

He meets up with her again when he attends middle school. Her name is Misaki Mei, and Koichi can’t help but notice how the other students and teachers at the school seem to treat her as if she doesn't exist. However, when tragedy strikes several of their classmates, she’s the only person who can help him unravel the mystery behind a string of accidental deaths.
