Ryo and Kaoru recently graduated from university. During a party, they recognize their feelings for one another. The two start dating, although they hide their relationship from family and friends. Initially, their romance goes smoothly. Ryo and Kaoru move in together, creating many special memories. From cooking homemade meals to taking baths together, the domesticated couple enjoys each other's company.

Ryo and Kaoru are struggling actors. They fail to land roles after auditioning many times. Feeling discouraged, Ryo decides to switch careers and settle for a stable office job.

Even though he spends most of the day at home, Kaoru prefers playing video games instead. The two boyfriends become increasingly dissatisfied with each other.

Another source of conflict is that Ryo hasn't come out to his family. Kaoru wants to meet his boyfriend's mother. However, Ryo has no intention of introducing his family.

Polyethylene Terephthalate Review


Drama Review Score: 7.1

Ryo and Kaoru started dating after university.

Polyethylene Terephthalate is a slow-paced drama that won't appeal to everyone. The narrative unfolds quietly without bold twists or exciting theatrics. Many scenes focus on the mundane, following the couple's ordinary day-to-day routine. The story imitates the rawness in real life, capturing the subtleties of emotions and intricacies of relationships. However, some viewers may not have the patience to endure the uneventfulness of the meandering plot. Compared to other BL series, Polyethylene Terephthalate isn't as entertaining.

Early on, Polyethylene Terephthalate showcases the couple's domestic bliss. From cooking homemade meals to taking baths together, the two newly dating boyfriends enjoy a delightful honeymoon period. While these interactions are sweet, they don't feel memorable. Each exchange seems vaguely similar, forming an indistinguishable blur of memories. The BL content is there, but it lacks persuasion. The series could have done a better job of highlighting romantic affection and intimacy. Nonetheless, the story successfully demonstrates that the protagonists are falling in love.

Afterwards, Polyethylene Terephthalate gradually introduces tension in the romance. Ryo's new career triggers a subtle conflict between the lovers. Likewise, Ryo's reluctance to come out of the closet causes further resentment. These complications add nuance to the love story. As the characters navigate various issues, I become more invested in their relationship drama. Also, the series' realism works in its favour. Ryo and Kaoru's problems resemble what gay couples may face regularly. Their disagreements feel relatable and reflect genuine experiences.

The second half of Polyethylene Terephthalate focuses on the couple's uncertain future. They tread ambiguously between a breakup and a reconciliation. The audience must speculate whether Ryo and Kaoru can resolve their differences. Will they capitalize on a second chance, or is their romance doomed? The title, Polyethylene Terephthalate, describes a material used to produce plastic containers. It's also a metaphor for the love story. Like an old water bottle, can a broken relationship be repurposed? This intriguing question is the central theme of the series.

Polyethylene Terephthalate shies away from melodrama. The feuding couple refrains from heated arguments or tearful accusations. Instead, the story takes a subdued approach to navigating the relationship issues. The leads are sometimes too stoic, making me wish they'd emote more powerfully. That said, Kaoru's actor (Hinata Asai) gives a sensitive performance at the end of Episode 1 and showcases his talent. Also, I'm impressed that he wrote, directed, and edited this series singlehandedly. Bringing a BL drama to life is no easy feat, so he deserves our respect.

Polyethylene Terephthalate suffers from rough production values. I'm most bothered by the audio inconsistencies, making it difficult to hear the dialogue properly. Likewise, the filming occurs inside a dinky apartment. Some visuals look unflattering, from awkward camera angles to drab interior surroundings. Nonetheless, I'll forgive these problems from a small indie studio with few resources. Despite the lack of polish, Polyethylene Terephthalate shines with its authentic storytelling. I appreciate this flawed BL drama for examining relationships maturely and thoughtfully.


Slow story

Polyethylene Terephthalate has a slow-burning plot that unfolds quietly. You may not have the patience to endure the uneventfulness. Yet, the story examines a couple's relationship drama thoughtfully.

Subdued romance

The series begins by depicting the couple's domestic bliss, albeit these exchanges are mundane. Soon, the story introduces tension between the lovers, diminishing the romantic atmosphere.

Delicate acting

The performers are sometimes too stoic, making me wish they'd emote more. However, Kaoru's actor (Hinata Asai) gives a sensitive performance at the end of Episode 1 and showcases his talent.

Sad ending

Polyethylene Terephthalate has a sad ending as the couple faces irreconcilable differences in their relationship. Yet, the final scene is open-ended. You may interpret the conclusion optimistically.

Unpolished artistry

A small indie studio produced this low-budget series with few resources. It looks rough and lacks polish in various areas. I'm most bothered by the audio issues and awkward camera angles.


Polyethylene Terephthalate is a slow-paced BL series that explores a couple's relationship drama with quiet dignity. Unfortunately, the rough production values detract from the viewing experience.

Hinata Asai (浅井日向) is a Japanese director who worked on the 2023 BL series, Polyethylene Terephthalate. In addition, he is the writer, editor, and lead actor of the drama.

  1. I rather enjoyed the "raw" nature of this BL drama. Having the story arc bend into the dissolution of Ryo's and Kaoru's relationship was a refreshing change from the standard "falling into love" trajectory of most BL themes.

    The indie look, accompanied by the fact that the lead actor of the 3 part series was also the series director, writer, and editor of Polyethylene Terephthalate, made me appreciate this series even more, due to what HAD to be the sheer amount of energy this cast and crew poured into this project; clearly a labor of love, with limited funds.

    Acting wise, [ALL SUPERB!] the degree at which facial looks and various body movements and body language were key storyline sources of unspoken dialog (as well as other private time together hinted at, but off camera), and this being so very very Asian in nature, let me relate to these characters much deeper, in what felt very familiar to my own life experiences, living in South East Asia.

    The realization by Kaoru, that his love of his life wasn't going to be willing to share his family with him, hit him the strongest, it seems. The relationship seemed to rather radically "pivot" from that point forward, making me review my own life experiences, wondering what specific instances had been pivotal, in leading to similar life decisions and changes, in my own life!

    Upon that "pivot point", that whole "chase" scene of Ryo chasing Kaoru, and ending in the garden area with them in clear view of each other, yet talking to each other via mobile phone… REALLY ran resonant with me; reflections of many times, of similar fights, arguments, pain and separation… as what was occurring here.

    Kudos to the actors and crew, for creating a memorable BL Drama!!! And much thanks for helping to fill in many plot blanks I had missed, making this BL Drama 2x more fun to watch!"
