Alice

I admit, they both show may be different in a way, but Hello monster is a first one, which I think about after watching Alice.
- both has a story with murders and the one who trying to find the trues;
- there are people with disorders, who choses different ways;
- mystery connected with relatives.
Alice is a modern one, Hello monster doesn't have science fiction part.

Jung Yeol and Na Ra fell in love with each other and got married. During their marriage, they have grown to hate each other due to their personality differences. They decide to get a divorce. A month later, their divorce will be finalized. But, on the day that they applied for a divorce, they get into a car accident. When they wake up at the hospital, they have both lost their memories and do not remember each other.

- Multiverse Theory.

- Both male leads are detectives.

- Mystery - crime dramas.

- In both, we find strange deaths.

1) Both the dramas involve time travel & parallel time lines (one set in 1992)
2) The main leads try to change the future for their loved ones
3) Both explore the consequences of tampering with time
4) There is mystery and romance in both
5) Both the dramas have beautiful cinematography

I'm recommending Life on Mars for Alice because both shows deal with police investigations, however Life on Mars deal with a detective who travels from the present to the past.

LoM has a bitter-sweet ending that you would not see coming where Alice had the beginning where you are like "Ok, what effect does this have on the future."

Both in mystery triller genre, include plot twists, things you never saw coming, relatively fast-paced and great plot.

Both deal with time travel/time dimension hopping

Both have ML in Police/Detective work

Parents love for their child is shown here/Both influence our ML

The three main characters (ML/2nd ML/FL) are all connected to each other like Tunnel

Both Family/Human Sci-Fi Drama

from the trailer both seem like time traveling mystery crime dramas about people trying to find justice through time

both are mysterious and about time travelling. People trying to change their life in a timeline to change the outcome in the future.

•Both dramas have the genres sci-fi and mystery
•Both dramas have a detective character
•While Circle isn’t about time travel, part of the story takes place in the future, which is a similar concept to Alice since the time travellers meet in the future (2050)

Same ML type as in Alice. Both have lack of feeling
or understanding emotions disorder. They don't process emotion
like average people can. Both have a Police officer as Main Lead.
