The Promise – 2022 Thai Series Review & Summary

The Promise 2022 is the prologue to the 2023 Thai BL series with the same title.

The Promise is the 2022 prequel for the 2023 Thai BL series with the same title. The main characters are university roommates who have been best friends for a long time. Their close bond makes others speculate about their relationship, although both deny having romantic feelings. As sexual tension builds between them, the protagonists have a massive fallout. Years later, they reminisce about the broken friendship and hope to resolve their conflict.

This short BL drama is divided into two parts. Each episode focuses on one of the protagonists, telling the love story from their perspective. The first episode, "Phupha", is emotionally charged. It highlights the anguish of unrequited love with heartbreaking confrontations and powerful performances. The second episode, "Nanfah", doesn't provide a satisfying follow-up. I would've liked more closure and reconciliation in the ending.

Others have noticed their close bond. They speculate whether Phupha and Nanfah may be romantically involved. Both guys are single and good-looking, so people appear interested in their love lives. Gigi, a student with a crush on Nanfah, talks to Phupha to clarify the rumours. He confirms they are just friends. Likewise, Nanfah insists their relationship is strictly platonic.

Nanfah wants to enter a dance competition. The grand prize is a trip to Vietnam. Nanfah coerces a reluctant Phupha to be his dance rehearsal partner. They attend lessons together.

However, his jealousy signifies Phupha doesn't see Nanfah as just a friend. There may be romantic feelings between them.

Years later, Phupha and Nanfah are no longer friends. Contrary to their promise, they lead separate lives and don't stay in touch. An adult Phupha comes across an old photograph of them together. He reminisces about their past memories, wondering where their friendship went wrong.

The Promise 2022 Review


Drama Review Score: 7.5

Phupha and Nanfah are in bed together.

This review is about The Promise, a 2022 Thai BL series. The first episode is titled "Phupha", while the second part is named "Nanfah". They are the prequels for the 2023 remake of The Promise, which has a similar plot with the same actors. You can consider The Promise 2022 an early prototype of The Promise 2023. In addition, the Thai version of The Promise has no relation to the 2022 Vietnamese BL drama with an identical title. There are three BL series called The Promise, but they tell different stories.

The Promise delivers a stellar first episode that exceeds expectations. The series has created a riveting emotional arc in only thirty minutes, which is no easy feat. This story begins by depicting a warm, authentic friendship. Phupha and Nanfah's cute dance lessons introduce the characters, highlight their personalities, and tease a romantic spark. The beautiful visuals and the actors' smooth chemistry enhance the alluring ambiance in these scenes. Between the enigmatic smiles and the loving gazes, The Promise quickly establishes a pairing that viewers want to champion.

The first episode focuses on Phupha's perspective, portraying the anguish of his unrequited love. He sees Nanfah as more than just a friend and feels tormented since his crush isn't reciprocated. Nanfah casually breaks his heart without even knowing what's wrong. Phupha goes on an intense journey with many ups and downs. He swings from distress to relief back and forth. His sympathetic experiences are worthy of pity, making you understand why he reacts dramatically at the story's climax. As his character agonizes, The Promise has my emotions in a chokehold.

Perhaps the first episode sets the bar too high, but the follow-up pales by comparison. The plot shifts to Nanfah's perspective as he reflects on his broken friendship. However, the romantic atmosphere has dwindled since the leads separated for a long time. They only interact in quick flashbacks, which are too short and lack impact. The story also introduces a new love interest who receives little development. Most of all, the events seem implausible. I'm skeptical as Nanfah approaches strangers to ask about Phupha. His efforts feel futile, like looking for a needle in a haystack.

Despite the declining quality, the second episode still contains delicate moments that tug at my heartstrings. This BL drama's strong suit is that it can evoke emotional responses from the audience. It helps that both leads give compelling performances throughout the series. Phupha's actor (Kun) carries his scenes with a versatile range, portraying his character's many fluctuating moods. He displays infatuation, rage, hurt, and desperation convincingly. Likewise, his costar (Kiak) has a gift of conveying melancholy. His wistful eyes can shimmer with unshed tears.

The Promise has a cliffhanger ending. It doesn't resolve tensions, leaves relationships undefined, and makes you ponder unanswered questions. Understandably, the prequel refrains from a definitive conclusion and saves the best material for the remake. The lack of closure is unsatisfying, like a book without a final chapter. We must wait until the new series for the rest of Phupha & Nanfah's journey. Overall, The Promise 2022 offers a promising preview of an epic love story. If it recreates the calibre of the masterful first episode, the 2023 version seems quite intriguing.


Riveting story

The Promise begins with an enticing first episode, depicting the anguish of unrequited love. The emotional story has many highs and lows. Yet, the second episode lacks the same impact.

Emotional romance

Early on, the series establishes a compelling bond between the leads. However, their romance becomes tortured as the story progresses. They hardly interact in the second half.

Powerful acting

Both leads give powerful acting performances. Kun displays a versatile range as Phupha, portraying his character's moods convincingly. His costar Kiak can also deliver melancholic emotions.

Cliffhanger ending

The Promise has a cliffhanger ending without satisfying closure. It doesn't define the leads' relationship or resolve their tensions. Instead, the story saves the best material for the 2023 remake.

Exquisite artistry

This series has beautiful visuals that elevate the romantic ambiance. I love the artistry of the kissing scene near the end. Everything looks soft and dreamy, like an ethereal fantasy.


The Promise begins with an emotionally charged first episode, backed by powerful acting performances & elevated artistry. The story falters in the second half and doesn't offer satisfying closure.

The Promise 2023 Series


The Promise (2023)

Namfah brings his face closer to Phupha.

The Promise released a ten-episode series in 2023. It is the sequel to the 2022 version, continuing Phupha and Nanfah's love story. The plot begins with the childhood friends reuniting after ten years of separation. Phupha integrates himself into Nanfah's life again, although he refuses to explain his mysterious disappearance. You should watch the 2022 prequel before starting the 2023 sequel.

The Promise 2023 is lengthier. Its eight hours of content are supposed to expand the story and develop the romance substantially. However, I'm disappointed with this lacklustre follow-up. The sequel fails to capture the same emotional highs as the original. The bloated plot has too much pointless filler and silly nonsense. Also, there are many annoying side characters and pesky love rivals. While the couple is still enjoyable, their relationship takes too long to advance. I enjoy the 2023 series as a guilty pleasure, but it should have been much better.
