SYNOPSIS

The Heart Killers (Thai: เขาจ้างให้ผมจีบนักฆ่า, RTGS: Khao Chang Hai Phom Chip Nakkha) is a 2024 Thai BL action-romantic-comedy television series produced by GMMTV and directed by Tichakorn "Jojo" Phukhaotong, the acclaimed director of "Not Me" (2021), "Only Friends" (2023), and "Gay OK Bangkok" (2016). The 12-episode series brings together Thailand's two most celebrated BL pairings: FirstKhao (Kanaphan "First" Puitrakul × Thanawat "Khaotung" Rattanakitpaisan) and JoongDunk (Archen "Joong" Aydin × Natachai "Dunk" Boonprasert), forming a single dual-couple narrative that became one of the most-watched Thai BL dramas of 2024-2025.

The story follows Kant Pattanawat (First Kanaphan), a charismatic tattoo artist and former car thief who works as a secret police informant in exchange for a clean criminal record. Tasked with infiltrating a pair of assassin brothers who operate a hamburger shop as their cover, Kant is shocked to discover the younger brother, Bison Aechitpol Phanlert (Khaotung Thanawat), is the man he had an unforgettable one-night stand with at a bowling alley. Bison's overprotective older brother Fadel Kasemsan (Joong Archen) immediately suspects Kant's motives, so Kant recruits his cocky best friend, mechanic Style Sattawat (Dunk Natachai), promising him a vintage car if he can seduce Fadel into distraction. Rounding out the cast are Babe (Ken Kanthee Limpitkranon), Lilly (Parn Thanaporn Waekprayoon), Keen (Pepper Phanuroj Chalermkijporntavee) and Chris (Peter Tuinstra). What begins as a calculated mission of mutual deception spirals into genuine love, devastating betrayal, and a five-year prison sentence that becomes the ultimate test of whether love can survive when it was born from a lie.

The Heart Killers is a loose adaptation of William Shakespeare's play "The Taming of the Shrew" (c. 1590-1592), filtered through the lens of the 1999 American teen film "10 Things I Hate About You." Filming took place from July 18, 2024 to October 30, 2024 in Thailand. The series premiered on GMM 25 on November 20, 2024 and concluded on February 12, 2025, airing every Wednesday at 8:30 PM Thailand time. The extended director's version streams on iQIYI, while the international subtitled version is available free on YouTube via GMMTV's official channel and on Rakuten Viki, GagaOOLala, and OneD Thailand. A novel adaptation written by Nottakorn was released on October 17, 2024 at the Book Expo Thailand.

KEY TAKEAWAYS

  • The Heart Killers is a 2024 Thai BL drama by GMMTV, directed by Jojo Tichakorn Phukhaotong, with 12 episodes that aired November 20, 2024 to February 12, 2025 on GMM 25.
  • Two superstar Thai BL ships in one universe: FirstKhao (First Kanaphan × Khaotung Thanawat) plays Kant × Bison, and JoongDunk (Joong Archen × Dunk Natachai) plays Style × Fadel.
  • Loose Shakespeare adaptation: based on “The Taming of the Shrew” with heavy inspiration from the 1999 film “10 Things I Hate About You.”
  • Dual mission-romance plot: police informant Kant and mechanic Style infiltrate two assassin brothers who run a hamburger shop, only to fall in love for real.
  • Where to watch The Heart Killers: free on GMMTV YouTube and GagaOOLala (with English subtitles), extended director’s version on iQIYI, subscription on Rakuten Viki, all with English subs.
  • MyDramaList score: 8.1/10 from 20,000+ users, with 38,000+ watchers, ranking among the highest-rated Thai BLs of 2024.
  • The ending: Bison and Fadel serve a 5-year prison sentence; Kant and Style become vocational teachers (art and auto-mechanics) inside the prison to stay close. The series ends with all four free, traveling, and Bison finally seeing the Northern Lights in Iceland.
  • Extended director’s version available: iQIYI streams the longer cut; the GMM 25 broadcast is the standard 45-minute TV version.
  • Tie-in novel: Thai author Nottakorn wrote a novelization released October 17, 2024. Unusually, it was written from the script rather than the script being adapted from a novel.
  • Director’s pedigree: Jojo Tichakorn previously directed “Not Me” (2021) and “Only Friends” (2023), two of GMMTV’s most critically acclaimed queer dramas.

EDITOR’S VERDICT

8/10

As someone who reviews countless Asian dramas, I can easily say that The Heart Killers is the most ambitious GMMTV project of the 2024-2025 season. Directed by Jojo Tichakorn, this 12-episode series successfully blends a Shakespeare-inspired romance with a gritty crime thriller, moving far away from the usual university settings.

The Cast & Chemistry

Bringing together Thailand's biggest ships, FirstKhao and JoongDunk, was a massive risk that paid off perfectly. The absolute standout is Dunk Natachai as Style. His dangerous, slow-burn chemistry with Joong Archen's calculating Fadel has rightfully taken over social media.

Meanwhile, FirstKhao anchors the show with their veteran chemistry as Kant and Bison, proving that high stakes and morally grey characters make for the best television.

Why It Works So Well

  • Real Consequences: Betrayals aren't just easily forgiven, and the 5-year time skip carries actual emotional weight.
  • Top-Tier Production: Sharp cinematography, realistic fight scenes, and a perfect retro-noir vibe.
  • The Uncut Experience: Skip the TV broadcast. The iQIYI Uncut version adds 15-30 minutes of crucial, intimate footage per episode that you absolutely shouldn't miss.

The Verdict

With an 8.1 MyDramaList rating and a gripping narrative, The Heart Killers sits proudly next to hits like Bad Buddy and Only Friends. It is a thrilling, perfectly paced masterpiece and essential viewing for any BL fan.

Final Score: 8/10

Will there be a Season 2 of The Heart Killers?

As of 2026, GMMTV has not announced a second season of The Heart Killers. The 12-episode story concludes with a definitive happy ending. However, the cast reunited for "The Heart Killers: Uncut" and "The Heart Killers: Behind the Scenes" specials, and a tie-in novel by Nottakorn was published in October 2024.

How does The Heart Killers end?

At the end of The Heart Killers, Bison and Fadel turn themselves in and serve a 5-year prison sentence after exposing their adoptive mother Lilly as the true villain orchestrating their assassination contracts. Kant and Style refuse to wait apart and become vocational training instructors inside the same prison, where Kant teaches art and Style teaches auto-mechanics, so they can see their partners daily. After release, all four travel together; Bison finally sees the Northern Lights in Iceland with Kant, while Fadel and Style relaunch the hamburger shop. Both couples receive a confirmed happy ending.

Is The Heart Killers based on a novel?

No, the original screenplay came first. However, a tie-in novel written by Thai author Nottakorn was released on October 17, 2024 by GMMTV Shop during Book Expo Thailand. Unusually, Nottakorn wrote the novel based on the existing series script, a reverse adaptation rather than the typical novel-to-drama format.

Is The Heart Killers based on Shakespeare?

Yes. The Heart Killers is a loose adaptation of William Shakespeare's play "The Taming of the Shrew" (c. 1590-1592), with significant inspiration from the 1999 American film "10 Things I Hate About You" (directed by Gil Junger), itself a modern retelling of the same play. The Style × Fadel storyline most clearly mirrors the Shakespeare/film source material.

Who directed The Heart Killers?

The Heart Killers was directed by Tichakorn "Jojo" Phukhaotong, one of Thailand's most respected queer drama directors. His previous credits include Gay OK Bangkok (2016), Gay OK Bangkok 2 (2017), Not Me (2021), and Only Friends (2023). Screenwriters include Yui Kanokphan Ornrattanasakul, Eng Issaraporn Kuntisuk, and Fleur Irene Insot.

What is the OST of The Heart Killers?

The official soundtrack of The Heart Killers is available as a Spotify playlist titled "The Heart Killers OST" containing all original songs from the series. The main theme song "Lonely" is widely considered the standout track and became a fan favorite associated with the Style × Fadel storyline.

How is the romantic content handled in The Heart Killers?

The Heart Killers carries a PG-13 rating with non-graphic romantic moments between both main couples (Kant × Bison and Style × Fadel). The GMM 25 TV broadcast and YouTube versions are the standard cut, while the iQIYI extended director's version includes longer 60-80 minute episodes with additional scenes. The series is appropriate for general adult and teen BL audiences.

Who is Lilly in The Heart Killers?

Lilly is the adoptive mother of Bison and Fadel and the primary antagonist of The Heart Killers, played by Parn Thanaporn Wagprayoon. She manipulated the brothers into becoming hitmen by orchestrating their biological parents' deaths and using guilt and dependency to control them. Her exposure and downfall in the final episodes is a key narrative beat.

Why is The Heart Killers so popular?

The Heart Killers gained global popularity for four main reasons: (1) it unites GMMTV's two biggest BL pairings (FirstKhao and JoongDunk) in one show; (2) it blends BL romance with crime, action, and prison drama in ways rare for the genre; (3) Dunk Natachai's breakout performance as Style generated massive social media discussion; and (4) the 5-year time skip and Northern Lights ending delivered emotional payoff that resonated with fans.

What is the rating and reception of The Heart Killers?

The Heart Killers holds an 8.1/10 rating on MyDramaList from over 20,000 user scores, with 38,000+ watchers and 273+ written reviews. It is ranked among the top BL dramas of 2024 and 2025 on global drama-ranking sites. Critical reception highlighted Dunk Natachai's performance, the action choreography, and Jojo Tichakorn's direction.

Are JoongDunk and FirstKhao real-life couples?

JoongDunk (Joong Archen × Dunk Natachai) and FirstKhao (First Kanaphan × Khaotung Thanawat) are professional GMMTV "shipped" pairs, partnered actors who appear together in BL projects. Neither pair has publicly confirmed a real-life romantic relationship; both are presented as professional collaborators. Fan engagement around their on-screen chemistry is a major part of their appeal.

How does The Heart Killers compare to Only Friends?

Only Friends (2023) and The Heart Killers (2024) share director Jojo Tichakorn and actors First Kanaphan and Khaotung Thanawat. While Only Friends is an ensemble friend-group drama centered on relationships in college, The Heart Killers is a higher-concept action-romance with a dual-couple plot, criminal underworld setting, and Shakespearean source material. The Heart Killers is generally considered more polished and tightly plotted than Only Friends.

What language is The Heart Killers in?

The Heart Killers is filmed in Thai, with the original native title เขาจ้างให้ผมจีบนักฆ่า (Khao Chang Hai Phom Chip Nakkha, literally "He Hires Me to Hit on a Killer"). Official English subtitles are available on all major streaming platforms including GMMTV YouTube, iQIYI, GagaOOLala, and Rakuten Viki. German subtitles are available on GagaOOLala.

What episode does Kant and Bison kiss in The Heart Killers?

Kant and Bison's romantic chemistry begins from Episode 1 with their bowling alley flashback. Their key scenes intensify across Episodes 4-7, with the relationship reaching emotional turning points around Episodes 7-8 when betrayals are revealed. Style and Fadel's relationship follows a slower-burn arc, with the most-discussed romantic payoff arriving in Episodes 9-12.

Does The Heart Killers have a happy ending?

Yes, The Heart Killers has a confirmed happy ending. After serving 5 years in prison, Bison and Fadel are released and reunite with Kant and Style permanently. Bison achieves his lifelong dream of seeing the Northern Lights in Iceland with Kant, while Fadel and Style relaunch the hamburger shop together. Both couples are shown happy, free, and committed in the final episode.
