This K-drama kept fans on their toes, trying to keep up with the countless plot twists and figure out who the real killer is. Is police officer Jeong Ba-reum (Lee Seung-gi) as innocent as he seems? Is Sung Yo-han (Kwon Hwa-woon) a serial killer like his infamous father, Han Seo-joon (Ahn Jae-wook)? An identity swap experiment and a brain transplant further complicate the story and leave audiences guessing about who the real killer is until the very end.

The premise of the drama is tailor-made for plot twists: Cha Ji-won (Moon Chae-won) is a homicide detective married to Baek Hee-sung (Lee Joon-gi), a timid, loving and devoted husband and father. But Baek Hee-sung is living under a stolen identity and hiding a dark, violent past. Throughout the drama, viewers are left in suspense, questioning whether he's a reformed man or a cold-blooded killer. The search for the truth leads to a locked basement, where shocking revelations about his past—and the real Baek Hee-sung—change everything. 4. 'Lovely Runner'

Not all K-dramas with a shocking plot twist are thrillers. Lovely Runner , a romantic comedy time-slip drama, packs a sweet and swoon-worthy surprise. While Im Sol (Kim Hye-yoon) spends much of the series travelling back in time to try and save Ryu Sun-jae (Byeon Woo-seok) from his tragic fate, audiences learn that it's actually Sun-jae who fell in love first and fell harder, long before she ever travelled back in time.

There's no shortage of jaw-dropping reveals in When the Phone Rings , a mystery romance that kept audiences guessing until the very end. Early on, viewers discover that Baek Sa-eon (Yoo Yeon-seok) was the one who arranged his marriage to his wife, Hong Hee-joo (Chae Soo-bin). Later on, they learn Hee-joo's selective mutism is just a ruse her mother came up with to save her skin. And when the kidnapper is finally unmasked, it's the identity of his accomplice that truly shocks fans of the drama. 6. 'It's Okay to Not Be Okay'

Pulsing steadily beneath the surface of this healing gothic romance is a psychological thriller that ties together Ko Moon-yeong's (Seo Yea-ji) tragic family history and the Moon brothers' (Kim Soo-hyun and Oh Jung-se) traumatic past. Audiences were stunned to discover that Moon-yeong's abusive and mentally unhinged mother is not only alive and hiding in plain sight, but also the one responsible for the murder of the Moons' mother.

In this K-drama starring Song Joong-ki as Vincenzo, an Italian mafia consigliere who returns to South Korea in search of hidden gold, the big plot twist isn't so much a heel turn as it is a heel reveal. Although a key character's death early in the series delivers a gut punch, the real shocker is the revelation that a Zumba-loving attorney and a bumbling and seemingly harmless law firm intern are ruthless criminal masterminds. Later, the death of a redeemed fan-favourite character delivers yet another emotional blow fans didn't see coming. 8. 'The Light Shop'

There are plenty of plot twists in this supernatural K-drama—from the fate of couple Yoon Sun-hae (Kim Min-ha) and Park Hye-won (Kim Sun-hwa), who choose to make their home in the place in between life and death, to Lee Ji-young's (Seol Hyun) haunting pursuit of Kim Hyun-min (Um Tae-goo), the man she cannot bring herself to let go of. But perhaps the most surprising and heartbreaking of them all is the tragic backstory of Jung Won-young (Ju Ji-hoon), the mysterious light shop keeper, and his hidden connection to mother-and-daughter duo Jung Yoo-hee (Lee Jung-eun) and Joo Hyun-ju (Shin Eun-soo).

In the K-drama set in Heaven, the appearance of Som I, a young woman with unknown ties to Lee Hae-sook's (Kim Hye-ja) husband Ko Nak-joon (Son Suk-ku), throws everyone for a loop, especially when it's implied that there's a romantic connection between the two. But audiences later learn that Som I is not a separate person but the manifestation of Hae-sook's grief and guilt over the son they lost, which leads to another emotional bombshell: the kindly pastor who befriends Hae-sook turns out to have a much deeper connection to her than she ever imagined.
