Yet another fantasy romance series -- “Tomorrow With You”-- is set to follow the recently concluded hit tvN series “Guardian: The Lonely and Great God,” which featured a hybrid of modern times and traditional Korean fairy-tale elements

A love story featuring time travel, mystery and intrigue, “Tomorrow With You” is a “a mix of genres,” according to its producer Yoo Je-won, who spoke at a press conference in Seoul on Monday.

“But it’s very heartwarming and comforting,” he said. “I hope viewers focus on the romance rather than the genre.”

“I tried to imagine a woman who exists in real life,” said actress Shin Min-ah. Shin portrays female protagonist Song Ma-rin, 31. Song is a former child actress-turned-struggling photographer who failed to continue her acting career into adulthood.

Song is easily annoyed and prone to excessive drinking, believing her best days are behind her. One day, miraculously and as if by fate, she receives a marriage proposal from Yoo So-joon, played by Lee Je-hoon, who appears to be the man of her dreams -- wealthy, intelligent and handsome.

Yoo, it turns out, is able to travel through time via a subway train. He journeys to the future to see what unfolds and returns to the present to prevent tragedy. He proposes to Song after discovering their destinies are inextricably linked, but ultimately discovers his abilities are limited when it comes to life and death.

“The subway becomes an important motif,” said producer Yoo. An intriguing point of the show is that “fantastical events happen in this mundane setting by which people travel every day,” he added.

Lee was excited to star in his first romantic comedy, a change of pace from “heavy, dark stories,” he said. The actor previously starred in last year’s critically lauded “Signal,” also a time-slip thriller series where investigators from the past and future communicated via walkie-talkie to solve crimes.

“Tomorrow,” a 16-episode series that has already been filmed, will begin airing on Feb. 3 at 8 p.m. on Fridays and Saturdays on cable network tvN. The show is available outside Korea via streaming sites DramaFever and Viki.
