Kairos (2020)

Both dramas have a similar concept. Both main characters use a device to contact a person from another time. In Kairos, it is a person from the future whereas in Signal it is a person from the past.

in both dramas the main leads are in different time lines and connect through a cell phone to try to change the past and the future. In this drama they are teenagers in the past and young adults in the present/future.

Both shows deal with characters in different time lines affecting a case. In Tunnel, the ML travels from the past into the future. In Kairos the ML is in the future but can communicate via a phone with the FL who is one month in the past.

Both involve the use of a phone as a time bridging element to change something that happens in the past. Both cases to save a loved one.

Story revolves around the child of the main leads. Thrilling, suspensful and lots of action. For this instance, the male lead involves in a battle w his former employer and has a limited time to save his sick daughter. Same theory w Kairos where the male lead tries everything he can to look for his lost daughter.

The cinematigraphy and the use of music is similar in these two. Top notch things. Really different plot, though.

similar storyline. how changing the past affects the future. theres two timelines in both shown and the stakes are high in both

Mystery, Thriller, married couple and a child… I don’t know why exactly but Flower of Evil reminds me of Kairos in a way. There’s one similarity I can think about but I don’t want to spoil it.

Well in reset it’s changing the present to change the future
