25 A Time Called You

Released In 2023

A Time Called You is actually a remake of a Taiwanese series called Someday or One Day, and it features more science fiction than just time travel. It also includes the characters jumping into the bodies of others and having their own doppelgangers. There is a lot going on, but it makes for a fascinating watch.

The series follows two sets of characters played by Jeon Yeo-been and Ahn Hyo-seop who see both their pasts and futures controlled by an old cassette player. The song on the tape player helps to control aspects of their lives, but not everything, leading to a lot of moving parts in the story. There’s even a serial killer subplot for those who like their K-dramas with a little mystery.

The only reason the series isn’t truly the best time travel K-drama is that the finale of the series doesn’t offer a full measure of closure, leaving some things open-ended for the audience.

24 Again My Life

Released In 2022

Again My Life isn’t the typical time travel K-drama. Rather than feature someone traveling straight into another time, the person is actually murdered early in the series, but then, the main character comes back as a college student. This actually works in his favor since in his previous life, he was a prosecuting attorney, so he’s already extremely intelligent and excels in the academic program, allowing him to spend his free time figuring out who set out to kill him.

Because this is one time travel series that is more of a thriller, there’s also an action element to it. Lee Joon-gi, who stars as the lead, has a black belt in taekwondo, and he does many of his own action scenes in the show instead of a stunt double. He won an award for his work on the show at the SBS Drama Awards after the show’s release.

23 Twinkling Watermelon

Released In 2023

There are shades of Back to the Future in this time travel K-drama as a teenage boy (Ryeoun) ends up in his father’s high school years. The boy and his father (Choi Won-young as an adult and Choi Hyun-wook as a teenager) don’t see eye to eye when it comes to music. While he wants to pursue a career as a musician, his father doesn’t think it’s a good idea. Their fight is the catalyst for the time travel experience.

While in the past, he finds that his father is desperate to connect with another young woman, not one who becomes his mom. He also realizes that his father isn’t hearing impaired as he is as an adult. He decides to try to prevent the accident that causes the hearing loss as well as make sure his father ends up with his mother, even as he’s forming a band with him.

It’s a heartwarming story about getting to know one’s parents and understanding how one decision can change everything.

22 Lovely Runner

Released In 2024

Those who enjoy K-Pop, athletics, and love stories will certainly enjoy Lovely Runner. The series sees a former superstar named Sun-jae (Byeon Woo-seok) lives a life of mostly isolation while his career explodes. Im-sol (Kim Hye-yoon) is a superfan who has been ing his career. In their 30s, however, they both wonder what their lives would have been like if they had done things differently. Of course, they also have a past connection.

When one of them dies, the other gets a chance to travel to the past to change their future, and it's revealed that they have both been doing everything they can to protect one another, even if it means their own lives might never be the same. The theme of the show is self-sacrifice as it explores what lengths someone will go to for someone they care about.

Interestingly, Beyon Woo-seok is not a trained K-pop singer, even though there are many artists who have crossed over into the acting world. Despite that, the song “Sudden Shower,” which was recorded for use in the show, charted, demonstrating that he’s got what it takes to lead a boy band.

21 Reborn Rich

Released In 2022

The last few years have produced a lot of hugely successful K-dramas that have reached an international audience. Reborn Rich, however, was hugely successful at home as well. It was the most-watched K-drama in South Korea in 2022.

Like Again My Life, this series sees someone who is murdered get a chance to start a new life in a new body, but with the awareness of their previous life. This time, it’s someone who is a hardworking employee at a chaebol - a sprawling family-owned business, the kind that truly runs the economy in South Korea. When he sees something wrong and tries to do the right thing, he is killed for it. He ends up returning to life as the youngest member of a chaebol family in an earlier time and starts putting his knowledge of the future to use.

While the bare bones of the two stories are similar as both characters want revenge on those who took their lives, the worlds they explore are very different. Reborn Rich was nominated for a slew of awards in South Korea and ended up winning for Best Miniseries at the Seoul International Drama Awards.

20 My Perfect Stranger

Released In 2023

When the two cross paths, they find that maybe their time traveling, and their lives, are actually linked to one another.

While most Korean dramas involving time traveling only see one character do the actual time traveling, My Perfect Stranger takes a risk in making both of its main characters time travelers. One does so on purpose though, while the other does not, which is where much of the intrigue comes from.

Hae Jun (Kim Dong Wook) is a journalist investigating a serial murder case who discovers a time machine and uses it to follow his own investigation. Yoon Young (Jin Ki Joo) discovers her mother dead and is then struck by a car, waking up in the same time that Hae Jun traveled to. As is true for many time travelers, they become trapped instead of able to travel between times. When the two cross paths, they find that maybe their time traveling, and their lives, are actually linked to one another.

19 Tunnel

Released In 2017

Instead of traveling to the past, Tunnel is a time travel K-drama that takes the audience to the future - in a manner of speaking. The present-day of the story is actually 1985 in which a string of murders are being investigated. When the detective (Choi Jin Hyuk) pursuing a lead runs after a suspect through a tunnel, he’s hit in the head and ends up 30 years in the future.

The murder mystery element of the series is inspired by a real string of serial killings in Korea, but the story is very much fictional. While the show presents itself as a murder mystery with a time-travel element, there’s also a romantic subplot and a family at the center of the story that makes it a drama that really shines. Incredibly popular outside of South Korea as well, Tunnel has been adapted for Thai television and an Indonesian remake is in development.

18 Familiar Wife

Released In 2018

A married man (Ji-Sung) with two kids is unhappy in his life. He’s depressed, hates his wife, and is unsatisfied at work. If he had only made different choices in his youth, he might have had a happier life. After traveling through a toll booth and losing control of his car, he winds up in the past and is able to change some of those decisions.

This is one time travel series that doesn't confine the protagonist to one time. Able to travel back and forth between the past and the present, he’s able to see how his different decisions have big outcomes later in life. It’s a similar concept to something like Sliding Doors but with many small changes to help someone understand their path in life. The music truly helps set the stage in the series as well with the soundtrack being nominated at the Korea Drama Awards.

17 Times

Released In 2021

Times isn’t a traditional time travel K-drama in which one character is transported to another time period completely. Instead, the time travel is a result of a phone line that is able to traverse timelines. Several series have used similar ideas, often with the use of radios instead of phones, with varying degrees of success.

Two journalists, one in 2015 and one in 2020, connect over the use of the same phone line. Initially, they work together to prevent the death of one of their fathers, but while investigating, they uncover a conspiracy that involves time travel and corrupt politicians. The series is definitely a unique take among the time travel shows created for Korean television, which usually focus on history and a romantic subplot instead of political intrigue. While the series didn't reach widespread acclaim, star Lee Joo-young was nominated for Best New Actress at the Baeksang Arts Awards.

16 Tomorrow With You

Released In 2017

While Tomorrow With You does use romance like most time travel K-dramas do, it also has a unique idea for the time travel itself. While most Korean time travel shows involve time traveling by accident, the main character in Tomorrow With You can decide to travel in time. It’s also done so while traveling the subway instead of falling through a portal or suffering a life-threatening injury in order to do it.

Yoo So-Joon (Lee Je-Hoon) takes on time-traveling adventures when he discovers that Ma-Rin (Shin Min-A) and he are linked by a tragic accident in the future. Intrigued by her, he decides to save both her and himself. He believes that he can change their fates thanks to his ability, but he has to figure out just how they are connected. He resolves to marry her in order to make sure, and they become truly linked as he falls in love.
