Can a Man Truly Love Just One Woman? Top Korean Dramas That Dive Into Obsession!

Love, in Korean drama, is never necessarily soft and easy. Sometimes it's brutal, all-engrossing, and so suffocating that it becomes nothing short of an obsession. It's the kind of story in which a man's heart comes to be fixed on one woman only — not because of habits, but by an overwhelming, unshiftable passion. These top-rated Korean dramas indulge in that breathless, gambly kind of love — the kind that never backs down even when it's supposed to. Whether romantic, tragic, or insane, these 12 dramas illustrate how obsession can look an awful lot like devotion… until it crosses the line.

1. The Glory (2022–2023)

Love isn't the point of it here — revenge is — but Jung Sung-il's Ha Do-yeong is obsessed with Song Hye-kyo's Moon Dong-eun in a way that's low-key, intensely obsessive. He's drawn to her pain, her strength, and the shadows she keeps. They have an intense, slow-burn romance that's haunting and deeply emotional.

2. Flower of Evil (2020)

What do you get when a man is fixated not on hurting, but on guarding the woman he cares about? Lee Joon-gi stars as a husband concealing his criminal life while scrambling to maintain his family intact. The tension, conspiracies, and pure desperation in this romance will keep you gasping for air.

3. Crazy Love (2022)

When a narcissistic CEO (Kim Jae-wook) fakes amnesia and winds up falling in love with his previously hated secretary (Krystal Jung), obsession and love are made into something utterly nuts and emotionally nuts. The title doesn't mislead — this one is nuts, but somehow it manages to work.

4. Cheese in the Trap (2016)

Yoo Jung (Park Hae-jin) is charming, rich, and disturbingly manipulative. His love for Hong Seol (Kim Go-eun) is sincere-looking — until you see how vigorously he tries to control her world. It's mind-gamey, convoluted, and utterly absorbing.

5. Yong Pal (2015)

Joo Won leads as an elite surgeon who quietly helps criminals — until he's smitten by a comatose heiress (Kim Tae-hee) trapped in a healthcare scandal. His passion to save her becomes obsessive, and obligation gives way to a fatal type of love.

6. VIP (2019)

What do you do when a man's obsession isn't on the woman he loves — but the one he's hiding? This melodrama explores infidelity, secrets, and the devastating consequences of loving someone wrong. Jang Na-ra shines in this slow-burn thriller of betrayal and emotional trauma.

7. It's Okay to Not Be Okay (2020)

Moon Kang-tae (Kim Soo-hyun) is a silent and introverted guy, but the emotionally tormented Ko Moon-young (Seo Ye-ji) becomes obsessed with him — and then he with her. Theirs is raw, flawed, and healing in its own strange way. It's a beautiful representation of obsessive love learning to breathe.

8. The World of the Married (2020)

This play shows what happens when love turns to revenge. Ji Sun-woo's (Kim Hee-ae) husband is obsessed with having it all — his wife, his mistress, his good name. The obsession isn't romantic — it's controlling, manipulative, and brutally frank about how love can be wielded as a weapon.

9. Mine (2021)

Possession, jealousy, and power whirl around this upscale drama. Lee Bo-young's character gets caught up in a secrets-ridden toxic love triangle. Men in this show fall deep — but at times due to the wrong causes, and always with consequences.

10. Strangers from Hell (2019)

This psych thriller is based on a distorted kind of obsession, as one man's descent into insanity is manipulated by the individuals surrounding him. Although not a traditional romance, Lee Dong-wook's character becomes deranged with an eerie preoccupation that goes beyond every moral limit.

11. Tempted (2018)

A modern-day version of Dangerous Liaisons, it is a seduction drama, a drama of power and obsession. Woo Do-hwan starts out wooing as a bet — but things soon become far more complex and sinister. It's a game of hearts and lives and deaths.

Seo Ye-ji returns in this tale of a woman's long-sought revenge — but the man at its center, played by Park Byung-eun, becomes ruinously obsessed with her. His love brings down everything he has built, and his inability to release her is his own undoing.
